We see what's presumably vodka next to a Russian officer. Koenig has some wine in front of him. Danilov and Khrushchev drink several shots of vodka. Koenig drinks some sort of liquor. Danilov and Vassili hide among many dead and bloody bodies, and Danilov's face is a bit bloody.
Blood squirts out as a person is shot, and then does so for another person who's shot in the head.
Vassili has a little bit of blood on his head after a close call with a bombing run. A man has a few bloody cuts on his face. Blood squirts out and splatters onto a wall and a second man as a soldier is shot in the head. A man who's been shot and wounded is bloody. We later see him with a bloodstained bandage on that hand.
