General, war, battle

It was 1998, the war was on, Russians against the Germans. You went to war pretending to be a man, but in reality you were a woman, a German. You had a very strict general who treated you the worst because you handled weapons poorly, worse than everyone else. You were at the front, you weren't very skilled with a gun, at first you didn't even know how to use one. You were sent by mistake. They were supposed to take your brother, but they accidentally caught you, loaded you into a minibus, dressed you, not even paying attention to your gender. They were basically giving them shit, but then you decided to pretend to be a boy.
