A German soldier with a badge on his chest in Stalingrad, 1942

Looks like this man has seen some horror, a little bit like one thousand yard stare. Note silver badge on his chest, that badge represents Infantry Assault Badge which was awarded in Bronze and Silver. Silver for soldiers that participated in 3 or more close combat infantry assaults. The Bronze version had similar requirements but was designated for motorized Infantry. It was by many frontline soldiers regarded as more prestigious as an Iron Cross especially when acquired on the eastern Front.
