IVF (Marder 2)

The IFV (IFV) Marder 2 was a prototype and planned successor to the Marder armored . He should be in terms of combat power and mobility in the battlefield between the raccoon and Leopard 2 close the gap. At its introduction in 1991, he was considered the most modern armored infantry in the world.

Development History

In the 1980s, recognized the leadership of the armed forces that the raccoon be combat efficiency potential would have reached soon. It was decided after long discussions the mid-80s, the re-tendering of a successor. Linked to the projectchariot 90 resulted in the following demands:

• Absitzstärke one of seven soldiers as minimum
• become fully operational with the Leopard 2
• Main weapon for fighting distances up to 2000 m
• partial protection against 30-mm bullets from machine guns (MK)

In June 1984, the tender was published with the demands. The tender saw between 1997 and 2001 before the procurement of 1,000 vehicles. After several concept studies we chose the 1988 proposal by Krauss-Maffei as a solution to the transport and combat vehicle PUMA could gain first experiences. Krauss-Maffei was general contractor (GC) for this contract. The company Rheinmetall from Dusseldorf was a subcontractor responsible for the subsystem tower with fire control and armament.Oerlikon Contraves with Heckler & Koch took over the ammunition supply.
By the fall of the Wall in 1989, the political environment changed drastically. In the context of the new global political situation - in particular the collapse of the USSR - a new armored personnel was seen as out of date. Given the costs of German unification , the abandoned Defense into volume production.
On 17 September 1991, the - until then unknown in the IFV-development - company introduced the first experimental support VT 001 still, but despite extensive tests and trials, the project in 1992 with the conclusion "too heavy, too big and too expensive" adjusted. For insider this compact-looking vehicle was a "space saver" - but t with a total weight of 44.3. The original Marder remained for several more years (with combat performance upgrades) the backbone of the armored infantry units of the Bundeswehr.
The prototype of the Marder 2 has since then alternately in the Army Technical Study Collection Koblenz or in tank museum in Munster for illustrative purposes.

Technical Description

Armament

As the main armament, the engineers used the machine gun Rh 503 with Doppelgurtzuführung to achieve the required combat distance of 2000 m. Unlike the Marder 1 the weapon system was stabilized. The lateral and vertical alignment of the main and secondary weapon was implemented via an electric leveler. In emergency operation was directed mechanically by hand. The lining drives enabled one side leveling range of 360 ° and a height indicative range of -10 ° to +60 °. The cadence of the main weapon was continuously variable from 150 to 400 rounds per minute.
Through the design of a double-caliber machine gun, it was possible to shoot with only through a tube change without further changes in addition to the 35 × 228-mm ammunition and 50 × 330-mm cylinder cartridges. The tube change took about five minutes. The ammunition feed is secured by a transport system gurtgliederloses from both sides. Ejecting the sleeves was in the weft direction. The electric drive of the third gun was jamming and interference reduction and increased reliability. Faulty and unexploded cartridges were ejected automatically. Disadvantage was the function of the energy supply of the vehicle electrical system. By Doppelgurtzuführung were two types of ammunition of the same caliber are fired in rapid succession.
As ammunition for both calibers two varieties were available. The anti used against hardened targets KE ammunition was developed by Rheinmetall APFSDS-T projectile ( Armor Piercing Fin Stabilized Discarding Sabot-Tracer ). It was an armor-piercing kinetic energy projectile with sabot and tracer . Against light-up (soft) unarmored targets an electronically programmable HE ETF floor (was High Explosive Electronic Time Fuze ) used. Developed by Diehl multipurpose ammunition was able on impact or at a distance of between 5 to 10 m above the ground to detonate. The settings have been made ​​immediately before the firing. In addition, a 50 mm caliber tracer propellant charge was added. The designation was HE-ETF-T. The entire ammo was in the prototype 287 cartridges, equivalent to 95.7% of the required supply of 300 cartridges.
As the secondary armament was in the army already established machine gun MG3 . It was parallel installed to the right of the main gun. A smoke grenade in caliber 76 mm with five throw cups on the left side of the tower and three launchers right of the machine gun shield allowed the crew to evade in combat the eyes of the opponent or the infantry squad during Absitzphase cover. An anti-tank guided missiles as its predecessor was not the prototype of Marder 2 provided.

Optics, fire control and aiming equipment

The Marder 2 disposal as well as a battle tank on a fire control system , which enabled the effective use of on-board weapons while driving. The pre-stabilized machine gun followed the values ​​of the stabilized level of the optics of the gunner and commander. The Marder 2 was considered to be all-weather and night battle ready.
The main target of the device gunner , the PERI-ZTWL 128/45 was used as a laser rangefinder, a day vision channel and a thermal imager . The acronym stood for ZTWL aimer, day vision, thermal imaging and laser distance measurement component - the numbers 128/45 stand for the entrance pupil diameter of the optics. The commander of the PERI-RT 60 via a separate independent Rundblickperiskop with day vision channel. For night vision, it was coupled with a thermal imaging channel with the thermal sight of the gunner. The acronym stood for RT panorama facility and day vision. Both workstations were redundant and had color displays.
It also featured the driver and gunner and the commander of three four -angle mirror for battlefield observation "in Luke." The infantry squad was equipped with three-angle mirrors on each side and one basic block in the two rear doors.

Protective Equipment.

The armor was designed modularly and consisted of the self-supporting body armor and additional armor. With the steel armor specific construction had a basic level of sides offered before hard-core bullets of caliber 7.62 mm and 155-mm artillery before splintering protection. The adapted additional armor increased to around protection against 14.5-mm, and at the front before 30-mm projectiles. The interior received a splinter shield to protect the crew in case of fire in front of the vehicle absplitternden parts of the armor. An NBC protection system also allowed for use in contaminated land.

Drive and drive

As drive chose Krauss-Maffei torsion bar sprung support roller drive, the suspension travel is limited by disk dampers and hydraulic stops. Each side it had six double tyred rollers. Due to the front-mounted engine to the drive wheel of the drive at the front. The track was as Endverbinderkette with replaceable chain cushions designed. The clearance was 440 mm, the bottom pressure 8.8 N / cm ². To facilitate the supply of spare parts and so the logistics, drive parts corresponded largely to those of the Leopard Series.
The diesel engine was developed by MTU Friedrichshafen and manufactured from the Leopard-1 -derived engine. The later in the Howitzer 2000 built MTU 881 Ka-500 delivers a maximum power of 735 kW at 2,700 rpm. The displacement of the engine is 18.3 liters, the maximum torque of 3000 Nm at 2000 rpm. Unlike his counterpart from the Leopard 1 is the engine of the Marder 2 not much substance capable . The total fuel level in the tank is 890 liters. On the road at speeds of up to 60 km / h were achieved in the reverse it was 27 km / h The power to weight ratio was 16.6 kW / t - that of the Leopard 2A4 20 kW /.
The power supply of 24 V electrical system was carried out by a liquid-cooled 20-kW generator. The battery system consisted of six batteries of 12 volts with 300 amp hours for the tub and four batteries of 12 volts with 90 amp hours for the tower.
The transmission was an automatic, hydromechanical transmission of Renk. Was coupled via a hydraulic torque converter with lock-up clutch. It also used in the howitzer 2000 HSWL-284-C-gearbox has four forward and two reverse gears. Through an integrated operating and parking brakes and through the integrated reversing and steering gear so that braking and steering was possible.

Crew

The crew of the armored personnel consisted of the three-person crew, and the seven-man infantry section in the rear. The driver sitting on the right in the vehicle and had access to the rear combat zone through a passage to the right past the tower. The commander and gunner were the right and left housed in the turret basket of two-man turret TS 503 by Rheinmetall. For the infantry squad two rows of seats were available for every three soldiers. The seat assembly was back to back. The seventh seat was located in the passage, and provided for the squad leader of the shooter squads. A hydraulically operated tailgate as the Marder 1 application found was not provided.The access to the combat zone was about two rear doors that open toward the vehicle center. According to the operational doctrine ofarmored infantry  - the fast switch between on and abgesessenem fight - four hatches were available that allowed the, fight over the side '.

IFV (Marder)

The IFV (IFV) raccoon is the main weapon system of armored infantry units of the Bundeswehr . In use are the Marder 1A3, 1A4 and 1A5. As the successor of the Marder IFV is Puma developed.

History

Development

The project was already marten in September 1959 during the incipient stage of the production HS 30 . The aim was to provide an "equivalent" to the armored Leopard 1 to develop. The ATV staff (training, engineering, testing) of the Armoured Troops School Munster created the military demands with the following features:

• Absitzstärke increased by 12 men
• high potential for protection of the crew
• high mobility, driving range Leopard a 1 equal
• a reliable 20-mm machine cannon
• straightforward exchange between on-and abgesessenem fight
• NBC

Moreover, it was intended to create an armored family, on the Kanonenjagdpanzer, Jagdpanzer missiles, 120 mm mortar vehicle, armored ambulance, armored, Flakpanzer, FlaRakpanzer and the lead tank air defense should build. Due to the fighting style of the armored infantry were, however, technical problems with the concept of the armored personnel carrier, the same should be the basis for all other platforms. The development of hunting gun and missile tank destroyer was to continue separately and in 1967 successfully completed. In January 1960, the group were Rheinstahl (Rheinstahl Witten, Rheinstahl Hanomag, engineers Warnecke) and Henschel AG (Thyssen Industrie AG Henschel Kassel) with MOWAG charged with the development of seven prototypes. As a result, several approaches have been presented based on the HS 30th The prototypes of the first generation were the RU 111, RU 112 and RU 122 of Rhine steel. 1HK 2/1 and 1HK 2/2 from Henschel and vehicles HM HM 1 and 2 of MOWAG All prototypes had a combat weight of 16 tonnes.
Due to the influence of the NATO partners, who demanded a say, and through a variety of proposals from other departments of the Armed Forces to test ran but slow. An agreement between the U.S. and the Federal Republic of Germany, to develop a common armored, was discarded.
In 1963, the list of demands for the second generation has been adjusted. This prototype was made ​​with a combat weight of 20 tonnes.Rheinstahl Group built the armored RU 214, RU 261 and RU 262 with front engine, improved tailgate, one-man turret with 20-mm machine gun and anti-tank guided missiles . MOWAG sat with their prototypes 2M1 / 1, 2M1 / 2 and 2M1 / 3 on a mid engine.
In 1964 came the third generation of the IFV with a new list of demands, adapt to the new needs of the Bundeswehr. The armored personnel carrier was longer and wider. In addition, the car got a heck-MG and ball covers on the sides for a weapons use under armor protection. As further recognition of the second generation showed that the one-man turret was not the right way. Suggest a two-man turret with scheitellafettierter was automatic cannon developed, which could be integrated without fundamental changes in the IFV.
In 1967, the last ten prototypes were developed and tested extensively in troop trials. The company MOWAG was eliminated in 1968, accounted for the boot device for a missile. After two years of successful tests of the 1969 series for the delivery of 2136 armored personnel carriers was signed. The first production vehicle was on 7 Delivered in May 1971 at the Panzer Grenadiers. Made the armored personnel were from the company Rheinstahl AG Maschinenbau Kiel (MaK).

Combat performance upgrades

During his period of service IFV was improved on several occasions in military parlance combat capability increased .
In the years 1977 to 1979 saw the first combat efficiency, the raccoon with all the anti-tank weapon MILAN were equipped. Their use was made ​​on or sold. Due on carrying four missiles the Absitzstärke drops to six men
In the same year with completion of the retrofit MILAN received all martens another combat efficiency. The upgrade included the installation of a Doppelgurtzuführers for the machine cannon for selective firing of explosive fire (English High Explosive Incendiary (HEI)) - or armor-piercing discarding sabot ammunition (English Armour Piercing Discarding Sabot (APDS)). Another significant change was the installation of better passive optics of the first generation. The included image intensifier was less sensitive to the spotlight and floor bolts.674 Marder 1 was updated to version A1 (+). This meant that additional equipment with a monitoring device on the basis of a thermal imaging device. With this it was possible to detect enemy tanks and at greater distances than ever before. 350 armored vehicles were on the stage Marder 1 A1 (-) brought. This in turn meant that these models did not receive any heat image-based observation optics, but were modified so that a retrofit would have been possible in the shortest time. The remaining 1,112 copies called Marder 1 A1A received no corresponding device and were not intended. The entire conversion was completed 1982nd
From 1984 to 1989 there was a renewed combat efficiency. This included the installation of a thermal imaging device (WBG) for the gunner, the elimination of the rear mount, the installation of the new family of radios SEM  80/90, the retrofitting of operating the MILAN-infrared adapter (MIRA) in the anti-tank weapon MILAN and angle mirror wash for driver. As part of this conversion, the name changed for all models of the weasel family to Marder first The name of the converted vehicles was Marder 1A2.
The next upgrade was seamless in the years 1989 to 1998 and included the improvement of passive armor protection, as well as the redesign of the assault crew compartment. So the hull front was armored, the hatch behind the driver disappeared. The rear hull roof was also armored and additionally received only three hatches. The tower, its apex carriage and the thermal imager were also armored. The total additional armor was thereby damped shock adapted flush on rubber elements. The sides have been supplemented with additional storage compartments, resulting in the elimination of the ball aperture result. The machine gun tower moved from right to the left side.The installation of a more powerful 720-horsepower engine has been omitted for reasons of cost. The entire conversion extended to 2097 infantry fighting vehicles, the name changed to Marder 1A3.
Furthermore, given some Marder 1A3 one crypto- and SATCOM -enabled SEM 93 . They are named Marder 1A4, but are externally indistinguishable from the Marder 1A3. They serve the commanders of mechanized infantry battalions as the lead tank.
In 2001, another small improvement followed by Rheinmetall Land Systems. This includes rearranging the ejector the smoke grenade and the programming of the controller for full use of the six cups. Due to the construction only five of the six cups were used. So the bottom-right cup was prior to the change so aligned that he lifted up the body hit the fog machine cannon. The name did not change.
A year later, on 18 December 2002, the planned since 1996 to combat efficiency Marder 1A5 began, it included the installation of a mine protective equipment by counteracting pressure blast mines and projectile-forming mines . These measures led to a further loss of mobility , while a total of 37.5 tons of weight gain as well as a complete overhaul and redesign of the rear fighting compartment, the package plan for the equipment, and a revision of the engine cooling system. Rheinmetall delivered the first of a total of 74 vehicles to the German Army. The Marder 1A5 are used in missions abroad, as well as a training vehicle in the schools of the army.
In December 2010, the first 10 marten 1A5A1 were delivered. They have space cooling system, jammers and multispectral Tarnausstattung, this equipment was designed especially for foreign missions, such as the Afghanistan operation. The space cooling system reduces the high temperature stress, while the jammer and the Barracuda Tarnausstattung increases with heat transfer system survivability.  Until August 2011 a further 25 Marder IFV been updated 1A5A1.

Marder 1

The Marder 1 is a front driven full-tracked vehicle. It serves the armored infantry combat vehicle and as the lead tank. By Kit VB and called Marder 1A3 VB he was in serious companies of mechanized infantry battalions until its dissolution as observation tank for forward observers (VB) of the angle of fire component ( armored mortar used 120 mm) and replaced the Kanonenjagdpanzer . The kit contains a TZG 90 A1 (portable target locator), a fire control type / Mrs MRI 86 (military computers, portable) and two SEM 90 (transmitter / receiver, mobile) and SEM 80 . The assembly of the TZG on the marten is possible with a suitable mounting bracket instead of MILAN, but it can also be used deposed.
Since the authority to operate at 31 December 2002, the Marder 1A3 VB replaced until the introduction of the new observation vehicle for the Joint Fire Support Teams (JFST) based on the fennec fox and Boxer and the optronic observation tank artillery on the M113. Since the Marder 1A3 is in the artillery observation tank is not as necessary reconstruction measures and would be too costly, it serves merely as the artillery troop transport vehicle. The designation is 1A3/ArtBeob marten.
In addition, the tub in the execution 1A3 as the basis for the driving school Marder, in slightly modified form in the Argentine armed forces under the name Tanque Argentino Mediano ( ger "Argentine moderate armor"), Vehiculo de Combate Transporte de Personal ( dt used "vehicle for transporting people in combat"). The air defense missile tank Roland also used a modified tub of martens, resembling due to the side storage boxes the Marder 1A3, but was designed differently.

Structure

The hull of the armored personnel carrier is made ​​of several varieties rolled welded steel tanks and designed as a solid armor. When the front, the sides and the rear of the crew are beveled and offer limited protection against fire from 20-mm machine guns (frontal), grenades and infantry weapons (to 7.62 mm). In addition, it reduces the effect of radiation. The attached since the Marder 1A3 additional armor was as Schott armor running and increased resistance at the critical points against shelling out 30-mm machine guns. To protect againstNBC weapons has the armored an NBC protective ventilation system with a capacity of three cubic meters per minute. For night driving, the driver has an image intensifier-propelled device that can be used instead of the average angle mirror. The commander and gunner are against the Marder 1A3 equipped only with a common thermal imaging device, which the commander of a light tube (English light-pipemay use).
Like the leopard family, the Marder 1 with a hydraulic submersible and is up to two meters tiefwatfähig .

Drive and drive

The armored has a torsion bar spring mounted support roller drive with hydraulic shock absorbers in the first, second, fifth, and sixth roller. He has a "living" Endverbindergleiskette with replaceable chain cushions the company Diehl . When driving in snow, on ice or to increase the grip of the chain, a part of the chain pads against cast iron snow grippers are exchanged.

Powered by a liquid-cooled V-6 four-stroke pre-chamber diesel engine of the type MB 833 Ea-500 with two turbochargers of the company, MTU Friedrichshafen , The engine reaches an output of 441 kW (600 hp) at 2200 rpm from 22.4 liters. It speeds up the Marder 1A3 from stage to a top official of 65 km / h The armored personnel to stage 1A2 reached contrast speeds of 75 km / h
Like the Leopard main battle tank, the drive system is designed as a complete engine block, consisting of motor and flanged shift, reverse and steering gear, which allows changing the complete drive train with the assistance of a recovery vehicle in a short time. The supply lines to the vehicle are equipped with self-sealing quick disconnect couplings. The cooling system is located to the vehicle, due to the front engine and the trunk lid, the fans sit right and left upwards in the rear of the vehicle. The system voltage is 24 volts, equivalent to the standard in the Bundeswehr. Generator is a generator with an output of 9 kW.
As a hydro-mechanical transmission shift, reverse and steering gear (HSWL 194) used the company Renk. Equipped with a torque converter with lock-up clutch, gearbox, steering gear shift and it also has a built-hydrodynamic flow brake ( retarder ). Switched to the four forward and four reverse gears by hand or with automatic switch, the gearbox is controlled electro-hydraulically. For the brake system is a hydraulic dual-circuit brake system .

Armament

The raccoon has a in the two-man turret housed 20-mm machine cannon (BMK) MK 20 Rh 202 , a turret machine gun (TMG) MG3 (7.62 mm) and a smoke grenade launcher with six throwing cups. Optional on the tower, a guided missile (LFK) type MILAN be mounted and fired.
The lateral and vertical alignment of the main and secondary weapon is via an electro-hydraulic straightening machine or mechanically by hand in emergency mode. They allow a page indicative range of 360 degrees and an elevation range of -17.5 degrees to +65 degrees. The recommended speed of the 3.2-ton tower is in normal operation, 180 ° for four seconds.
The main weapon to be used against unarmored targets up to a distance of 2000 meters. Here comes the explosive incendiary ammunition (HEI) is used. Against lightly armored targets at 1000 meters sabot ammunition (APDS) is used. The use against heavily armored targets is possible in good conditions below 600 meters. When fighting a battle tank is the aperture with HEI possible to allow the use of MILAN and the armored infantry. A fire with armor-piercing ammunition is unsuccessful. Against air targets the area of influence is limited, and it is used then only against directly attacking destinations. The maximum engagement range is up to 2000 meters in helicopters and jet aircraft up to 1200 meters.
The maximum range of the main weapon of the struggle lies unabhäng distances at 6,000 to 11,000 meters.
For maneuver , the entire tube is exchanged for a blank firing device (MDD). This is a lot thicker and visually resembles the tube for sharp weapons use, but is closed at the end of the tube. The safety zone in front of the weapon is to maneuver ammunition and blank firing device 10 meters, 70 meters without MPG.
The secondary weapon is tracked parallel to the main weapon. The modification to the Marder 1A3 MG3 sitting left outside the apex mount. Installed into a tank weapons the MG3 is fired electrically and used against infantry.
Furthermore, in the rear can battle space housed armored infantry from three hatches over the side with their hand weapons (G36, MG3,MP2A1 , Granatpistole 40 mm ) and can also be used to fight dismounted.

Occupation in the Marder 1A3

The crew consists of at the armored infantry: commander , gunner (both in the tower), driver (the front of the tub), and six grenadiers in the rear combat zone, as follows: Troop Commander ( G36 ), contactors 1 ( MG3 ), contactors 2 (G36 + MILAN ), contactors 3 (G36 + MILAN-loader), contactors 4 (G36, PzFst3 ), Sagittarius 5 ( Sniper ).

The task of the commander is to manage the tank or the group. This he observed from the tower of the present site, and can engage with the turrets into battle. If the primary use in dismounted combat, he leads the infantry squad, while the squad leader takes his place in the tower.
The job of the gunner is to use the turrets to observe the surrounding terrain with the optics of the carapace, and the radio traffic perform.For directing the turrets have commander and gunner via one Periskopvisier dual and six times magnification and on the common thermal imaging device. The operation of the tower is carried out via hydraulic motors which are powered by a 108-bar-hydraulic system. In the event of failure of the hydraulic system allows the gunner set the tower on winches and build a hand pump hydraulic pressure for additional functions.

Badger (armored) (Dachs )

The Badger armored engineering 2A1 or Pionierpanzer badger belongs to the group of combat support vehicles and is the successor to the pioneering Tank 1 . He is an armored pioneer work unit and is based on the Leopard 1 chassis. His responsibilities include: the recovery of damaged vehicles, the manufacture of entries and exits as well as entrances and exits to water crossings or steep and muddy coastal waters, the Befahrbarmachen the water bottom and the donning and removing obstacles and barriers on the battlefield. Used the vehicle with the pioneers and pioneers of armored army the army and in theCanadian armed forces under the name Badger - Armoured Engineering Vehicle (AEV) . He also is used in the Chilean army.It is the first pioneer by the Bundeswehr, which has been optimized specifically for the applications of the pioneers.

Development

After the failure of the project armored pioneer machine (GPM), the Bundeswehr still sought a successor for the first Pionierpanzer According to the mission fields of the pioneers , the conveyance of the movements of one's own fighting force and inhibiting the enemy by creating barriers, should all work at ABC - and armor protection to be executable. Was requested by the Ministry of Defence (MoD), an inexpensive full-fledged armored engineering that takes into account the experience of the GPM project. The total contract value comprised 140 vehicles with a total value of 190 million DM delivery target was 1990.
The company Maschinenbau Kiel (MaK), built in the period from 1981 to 1983 his first two prototypes and tested them in 1984 in experimental work. The third prototype was followed in 1987 after contracting by the Federal Office of Defense Technology and Procurement . The design of MaK based on a modified Bergepanzer 2 and received, instead of the crane with a telescopic bucket company Wieger Maschinenbau. The error-prone for the drill Engineer Vehicle 1 was not pursued. The ironworks Kaiserslautern (EWK) appeared responsible for the swing and the dredger. Jungenthal Jung took over again - just like with the GPM project - the renovation of the trucks. 75% of the components of the Leopard series found themselves in the roof. The combat weight t reached the 43rd
MaK made ​​as a general contractor in 1988 the armored engineering. According to the planning objective of the MoD this arose from the conversion of 104 armored recovery vehicle 2 and the existing 36 Pionierpanzer first The first production vehicle of armored engineering 2A1 roof was on 13 April 1989 passed in Ploen, ahead of the target delivery of the Bundeswehr. Labeled A1 has been chosen to demonstrate the performance of the assembly relative to the recovery tank. The ladder on the telescopic arm and the bow MG accounted for roof and was only found on a prototype. The proven hydraulic and mechanical cutting angle was dropped also. Delivered a total of MaK - since 1992 a part of Rheinmetall Land Systems - 149 vehicles of this type in Germany and Canada . The Order of Canada for nine vehicles had a value of 49 million DM.

Technical Description

Interior and occupation

The crew consists of three men: the driver, the commander and a third crew member as an additional work force. The driver sits in the front right vehicle under a one-piece hatch. He controls the tank according to the specifications of the commander and served the pioneering technical institutions, including the sign, and the winds. He is also responsible for maintenance on the hull of the tank. The commander sits slightly to the left directly behind the driver. He leads the tank, keeps the radio connection to the higher-level management positions and may, if necessary to override the driver in control of the telescope. He is also responsible for loading and operation of the anti-aircraft machine gun. Third soldier sits in the rear part of the structure. The access to the combat zone via the two skylights or the hatch on the left side of the vehicle.
To have the communication vehicles of the Bundeswehr with a VHF SEM 80 (transmitter / receiver, mobile 80). All angles are in the range of implements mirror mounted to tilt in order to work under armor protection. As night vision devices used intensifier .

Protective Equipment

The trough of the roof is made ​​of welded steel armor and has a single-layer armor. The level of protection for the chassis is similar to the Leopard 1 The armored structure reaches armor thickness from 25 mm to 35 mm and 10 mm for the sides of the roof. The hydraulic cylinder of the telescopic arm received a splinter protection. The standard equipment include a NBC protection - and ventilation system and a fire detection and suppression system. The exhaust system with air infiltration, reduces the infrared signature and thus supports the passive armor protection.
The Canadian Pionierpanzer also received for the KFOR and ISAF deployment provides MEXAS additional armor from IBD Deisenroth Engineering .

Armament

The armament of the roof is mainly intended for self-defense. The three-man crew of the German armed forces has a machine gun MG3on the anti-aircraft gun mount the commander's cupola, a smoke grenade launcher with six cups and throw their hand weapons . The Canadian Badger additionally comes with the bow gun. As a machine gun there is the Belgian FN MAG under the name C6 GPM .

Engine and chassis

The torsion bar suspension support roller drive of the leopard was adopted without changes. Each side it has seven double-tyred rollers and four support rollers. The suspension travel is limited by volute springs and stops. The drive wheel is at the back of the chain.

To avoid the loss of the chain, driving in difficult terrain ', received the prototypes on large discs on the drive wheel. The series vehicles were equipped with chain start carriers (driving wheel cleaners), which are attached as required across the drive wheel drum. When not in use it can be stored on the rear right tail. As a caterpillar is a "living" Endverbinderkette (type: D 460A ) with interchangeable chain upholstery manufacturer Diehl. The ground pressure is 0.92 kg / cm ².

The complete drive train was also taken one to one. Powered by a 10-cylinder multi-fuel engine of the type MB 838 CaM-500 with two mechanical chargers reached the roof a top of 62 km / h The engine delivers 830 hp at 37.4 liters capacity and allows a power to weight of 19.3 hp / tonne. The fuel supply of tanks was increased to l 1410th The street range is therefore 500 km, with a consumption of 280 liters per 100 km. To ensure a steady supply of oil even in difficult terrain and in an inclined position, the engine is a dry sump forced lubrication equipped.

The power supply of 24 V electrical system is provided by a liquid-cooled 9-kW alternator. The battery system consists of six batteries of 12 volts with a total of 300 amp hours.

Power is transferred to the chain uses the badger the Manual 4 HP-250 by ZF Friedrichshafen . Flanged to the engine, it has four forward and two reverse gears are shifted electro-hydraulically. Is coupled with a hydraulic torque converter lockup clutch. The brakes of the vehicle meets the minimum requirements of the Road Traffic Licensing Regulations and are designed as a single-circuit hydraulic disc brakes with brake oil pump support and nitrogen reserve.

Pioneer Equipment

The heart of the roof is his pioneering features. These include the telescopic arm with bucket, the clearing and support plate, the mountains and wind equipment and various means such as a pioneer of cutting and welding equipment and work lights. The hydraulic system has been improved in performance and works on the load-sensing principle, which means that multiple hydraulic cylinders (up to three) can be operated simultaneously and independently of each load. The working pressure is 300 bar.

A special feature of the Engineer Vehicle 2 is the possibility of using an underwater elevator shaft and special preparations are working on engine and chassis even in a water depth of 4 m in continuous use. The control of the telescope is done by remote control from the bay.Without these measures, the working depth is 0.8 m and 2.25 m in Tiefwatausrüstung. A flushing the back of the battle space, originally designed for armored pioneer machine allows, also working in very dirty and fast flowing water. The circulating water is used for cooling of the engine and hydraulic oil.

As with the prototype of the GPM of the EER excavator plant was installed front right of the chassis. The similarity of the Teleskopbaggerarms is the most prominent feature of this design by MaK. The extendable to 9.20 m in length construction allows a swivel range of 195.5 °, and a rocking angle of + / -60 °. The earthworks are incurred bucket with teeth and drain holes are available. The capacity is 0.6 m³ to 1.1 m³. The excavator output reaches 140 m³ / h, the tensile strength of 125 kN. By a clamping device with twoclaws can beam, trees and other obstacles are removed. An optional device may be on the arm with the bucket used as a third claw together. In addition, the dredger will be used by the pioneers also for pressing and tearing.

Zurüstbarer a swivel hook on the telescopic arm also allows use as a crane that allows you loads of up to 7.8 t at 3.98 m radius and up to 2.6 tonnes at 7.92 m can raise throat. Through a technical change, the maximum load has been over the use of reduced time t 2, in which case the bridge area of the tank Quick bridge beaver t with 2.5 considered to be exceptional load. When an overload in crane operation, an overload warning system stops - which are reset manually by the operator must - crane operations.
The shape of the rough and support shield was selected for the working areas of the pioneers and can be expanded by folding extensions of 3.25 m to 3.75 m. The cutting angle is 50 ° fixed, the height 94 cm. Equipped with a tear, which loosens the material and swirled can antitank ditches and pushed obstacles. The clearing capacity is 270 m³ / h Applying a fight prior to a battle tank takes about 15 min  to complete. Two zurüstbare fangs enable on-demand in driving backwards to a depth of 45 cm and a soil loosening. The dredging and use of wind shield serves as ground anchors, thus ensuring a stable level of pioneer tank.
The wind plant was built by MaK unchanged and an improved chuck adds that provides for winding and unwinding a uniform cable tension. The tensile force of the winch drum is 345 kN (34.5 t) in the single drawing and 690 kN (69 t) in the double move with pulley . The operating speed is 14 m / min in the first gear and 44 m / min in second gear. A role above the Räumschildmitte reduces the wear of the 90 m long and 33 mm thick rope rolling. When used underwater, the cable drive are covered and therefore not usable. The Canadian has Badger notwithstanding a capstan winch with a pulling force of 350 kN (35 t) in the single drawing.

Other features also include a cutting and welding machine (54 V/360 A), angle grinders , impact wrenches , car lifters, pulleys, towing scissors, shackles and hand tools in addition to an expanded set of tools. The loss of internal storage space was offset by three boxes on the vehicle, which was supplemented in 2009 with the German armed forces through a waterproof storage box in the engine cover. Lockable tool boxes on the hull sides should also protect against loss and damage to the equipment in use.
