At first I thought this was made out of cardboard. XD

No but from the amour protection it comes pretty close .

Small thing.

Or self-propelled artillery as i said . Of course it wasn`t planed with extreme amour , what would probably broke the chassis of the light Pz2 anyway , but you don`t expect the arty to get close to the enemy do you ? Still better that the Marder series of "case of need" anti tank vehicles that had to fight vehicles , like tanks , that could kill then with one shot because that vehicles were not better protected that this one , with limited protection against small arms and splitter .
