Panzerjäger 38 (t) "Marder III"

This German tank destroyer was built on the chasis of the reliable Czech tank Panzer 38 (t). It fought  in all

fronts, demonstrating the effectiveness of its 7.62cm Pak 36 gun. Its lack of thick armor gave it speed and mobility, but also vulnerability and most of them succumbed to enemy fire as artillery, tanks or bazookas... 

It was in use till the end of the war in 1945.
