What a joke this film is technically.
They find a building and huddle together in one location.
A perfect target to be taken out, all at once. You never hide in a building or structure the way they did.
And the Germans, well at the end of the movie, I guess the Germans didn't have any mortars, the Germans were well known for their expertise, accuracy, they could drop a mortar down a chimney pot! Why didn't they take out the barn with that flamethrower right away? And why didn't the Russian "Crack Team" break the ladder outside or lift it into the barn, just in case? Duh!
What a joke!
