That moment you're surrounded by a bunch of Ruskies chanting Ora Ora Ora over and over, your armor has been knocked out, their armor is advancing, they have full air superiority, you've ran out of rations and are on the verge of running out of ammo.

Just before the battle you notice one unopened ration case in the mud and smile. Opening it you discard the food despite your severe hunger and pass the pervitin around to all the boys.

The Russians see you doing this and hear the Popeye theme, immediately trying to withdraw but it is too late. They're dead.
