The narrator tells us that this guy will not leave the army if he doesn't learn a lesson. He's still defending him, he tells us, even though he's been beaten up many times. This guy can make you give up, he says, and he can even make you fight him if he needs to. The narrator says that this is bullying, because the guy saved him from a bomb explosion during a drill. He says that he'll find out how to make speeches like this after his training ends.
