Just Some Thoughts...
I would just like to express my view that basic training was not portrayed in a accurate way due to the fact that the film was biased, or so to say, on Bozz's part. I guess the film wanted to portrayed Bozz as an innocent victim. And so I must elabarote so that ye may understand my point.
-The first scene depicting how the day of a recruit starts does not capture the intensity of basic training. From my experience in the army, I would say the scene is too passive, the soldiers dress too slowly and are lazy, in reality, the wake up call started a race, an amazingly intense and confuse race -- and the last soldiers to leave the barracks would get punished. Either by getting hit really hard with a stick or by doing exercise. Not to mention that if you were last your buddies and superiors would start picking on you.
So the first scene of the film was unrealistic. Now I would like to move on to another scene that bother me. The scene when Bozz meets a Captain in his office, after Wilson tries to kill him, and Bozz has all that hair in his face. Its obvious he hadn't shave, and I don't know about the US army, but in the Colombian army, that captain would have punished Bozz for being unclean.
Another thing that greatly bother me was the amount of fights in the film. In reality, fights in the army aren't very common due to the severe punishments that people fighting suffer. A soldier who fights during Basic will probably not sleep much the whole week, and work out literally till he loses conscience.
Furthermore, a soldier like Bozz would never go out on leave, he'll probably be guarded all the time, would probably be hated upon by his partners, since due to his stupidity, they would suffer (in the army, for the mistake of one, the whole platoon pays, something the film didn't depict), and because he is hated by his partners, they'll probably steal his clothes, helmet, food, etc, and Bozz would never be a squad leader, because no one would listen to him, simply by the fact that he didn't listen to no one and made his platoon suffer.
Someone like Bozz would be forced to change in the army, he would be force to obey, he'll be broken down by his superiors, his fellow soldiers, and the system.
