Keeping the weight within the 35-ton limit also led to a smaller calibre for the secondary armament, a coaxially mounted 5.56mm HK MG4 machine gun firing at 850 rounds per minute and with an effective range of 1,000m. The ammunition capacity is 2,000 rounds; 1,000 ready to fire and 1,000 in storage. While this is a smaller weapon than the western standard secondary armament ( 7.62 mm caliber MG), it offers the advantage that the crew can use the ammunition in their individual firearms. In situations where the lower range and penetration of the 5.56mm rounds is an issue, the high ammunition load of the main gun enables the vehicle crew to use one or two main gun rounds instead. The gun housing can also host the 7.62mm MG3. The MG4 is being replaced by the MG5 with the S1 variant. [4] Grenade launcher [ edit ] Traditionally, IFVs are expected to interact with main battle tanks (MBTs) on the battlefield. In reality, many IFVs are not mobile enough to keep up with the pace of an MBT. The Puma aims to close this gap with several key technologies. Firstly, its compact, lightweight MTU Diesel engine is unusually strong at 800kW nominal output. Even at the 43t maximum weight in protection class C, it has a higher kW/t ratio than the Leopard 2 MBT it is supposed to supplement. With these specifications in mind, a number of considerations were further researched. Two core crew members, large degrees of automation, and the same mobility as the Leopard 2A4 were all considered. In addition, diesel-electric drives, active protection systems (hard and soft), digital on-board network, effective mine protection, and high performance shells were thought to be important for the design constraints.

At a price of 17 million Euros per unit, the Puma is the most expensive IFV in the world. In addition, due to the increased weight parameters during development, the Puma requires increased transportation for its modules that make it combat effective.The Puma has access to an infra-red jammer, the MUSS APS. It is a constant active APS which provides protection against a wide variety of threats. The jamming device (commander's optics like system on the highest mount of the turret's roof) is mounted on the roof of the tank to cover the vulnerable frontal arc. It is called "Infrared Countermeasure" for the following reason: SACLOS guidance utilizes a beam-riding guidance which is connected to the GPS (gunner main sight in some cases, on others it is a different sight like on T-55AM-1 and T-62M-1) which uses a flare as reference point for the guidance system in the ATGM. The missile moves with the gunner's sight and the flare tries to stay on the crosshairs. IRCM confuses the GPS with a brighter IR light decoy acting as the flare (the flare is also IR) which signals the ATGM to move to a different position nowhere near from the gunner's target. The system works in a similar fashion to the Shtora system found on the Soviet T-90A and the EIREL system found on the French AMX-30B2 BRENUS. With costs as ballooned as they were, other armies within Europe, most notably the Dutch army, decided to stop using German IFVs and switch to the Swedish Combat Vehicle 90. There are provisions for hard- or soft-kill systems to defeat hostile ATGMs or RPGs, or for future active/reactive armor. There are also mounts and interfaces for the inclusion of ATGMs on the right side of the turret.
