Demobbed (2000)

The student, Bayonet, has managed to seduce his professor's wife, Bomb, an average working guy, has bought a factory and Bullet, the casino lover, is hiding from creditors. They all share a common path and conscription. In the army they teach you that everything must be smart and in order - cockades, straps and all, otherwise you're not fit to call yourself a person, you're a maggot. For a real man, there's no better place than the army.
