My dad told me about some book he read where an American was captured by some Russians. They basically just gave him a rifle and vodka and were like "you're one of us now". He said they got strafed a few times by German planes and he dove into the ground on instinct while the russians just lifted rifles and shot at the plane the whole time. People got killed, plane left, and they'd just keep marching. They thought it was funny the american was diving into the ground and were giving him crap, laughing at him.
Different culture I guess.
