You just walking down the street at night, people around the street quite a lot, so u don't really feel like there's gonna be a jerk around here. You bumb into a man, well dressed in a uniform, clearly a sergeant and clearly drunk, the man did not even move for a second before he fall to the ground himself. From his face you can know he's a Drill sergeant, because you know what Drill sergeant looks like, you become a soldier once, defending the Soviet union.
