ordered by the German military. Eighteen Pumas took part in exercises in 2022, and all of them were inoperable at the end of the exercises. Major General von Butler, the commander of the 10th Armoured Division, described the situation as a "total failure." Consequently, the German government has paused purchases of further Pumas. The manufactor described the damage as "minor damage" which "was caused by the crew through improper operation" Design The Puma, while externally not very different from existing IFVs, incorporates a number of advances and state-of-the-art technologies. The most obvious of these is the incorporated ability to flexibly mount different armour (see below for details). Another feature is the compact, one-piece crew cabin that enables direct crew interaction ("face-to-face"; like replacing the driver or gunner in case of a medical emergency) and minimizes the protected volume. The cabin is air conditioned, NBC-proof with internal nuclear and chemical sensors and has a fire suppressing system using non-toxic agents. The engine compartment has its own fire extinguishing system. The only compromise of the otherwise nearly cuboid cabin is the driver station, located in a protrusion in front of the gunner, in front of the turret. One measure to achieve the one-piece cabin is the use of an unmanned, double-asymmetrical turret (see photo): while slightly off-center turrets are common in IFVs, the Puma's turret is on the left-hand side of the vehicle, while the main cannon is mounted on the right side of the turret and thus on the middle axis of the hull when the turret is in the forward position. The outer hull (minus the turret) is very smooth and low to minimize shot traps and the general visual signature. The whole combat-ready vehicle in its base configuration will be air transportable in the Airbus A400M tactical airlifter. Its 3+6 persons crew capability is comparable to other vehicles of comparable weight, like the US American M2 Bradley IFV, the Marder, and the CV9040, but smaller than the 3+8 of the CV9030 and CV9035. Armament The primary armament is a Rheinmetall 30 mm MK 30-2/ABM (Air Burst Munitions) autocannon, which has a rate of fire of 200 rounds per minute and an effective range of 3,000 m. The smaller 30×173mm cartridge offers major weight saving advantages over, for example, the Bofors 40 mm gun mounted on the CV9040 because of a much lower ammunition size and weight. The belt feed
