I hope you were'nt litaral about he's learning how to kill.
You are trained to kill a human being in all branches of the military.
However, he won't focus a lot on that-unlike Marines. Marine boot may sound hellish and hard, but if you shut your mouth and do what your DI's tell you to do, then you're fine. Teamwork is also essential in making it through boot camp . . . no teamwork = you are in a world of shit. You should also be physically fit before you enlist. It makes life easier . . .
I recall past friends saying how boring boot camp was. Ramsus is "aiming high", he'll be just fine. Air Force boot is the easiest and it is only 6 weeks.
