The basic armour can resist direct hits from 14.5mm Russian rounds, the most powerful HMG cartridge in common use today (and up to twice as powerful as the western de facto standard .50 BMG cartridge) and is said to defeat simple hollow charge warheads. The front armour is at least able to withstand 30mm AP projectiles. In protection class C, the flanks of the Puma are up-armored to about the same level of protection as is the front, while the roof armor is increasingly able to withstand artillery or mortar bomblets.
т.е. в базовом варианте борт держит 14.5 и старые рпг, лоб держит 30мм и более мощные рпг
в варианте С защита борта доводится до защиты лба
ещё в варианте-С усиливается крыша и башня

Another crew safety measure is that the main fuel tanks are placed outside of the vehicle hull itself, mounted heavily armored within the running gear carriers. While this may pose a higher penetration risk to the tanks, it is unlikely that both tanks will be penetrated at the same time, enabling the vehicle to retreat to a safer position in case of a breach. There is also a collector tank within the vehicle to secure steady fuel flow which may act as a reserve tank in case of a double tank breach.
топливные баки расположены снаружи основного забронированого объема, возможно они также включены в схему бронирования
