Is this army naval or air force? Different things apply in each, eg you have to swim a certain distance in a certain time for navy and be under a certain height and weight for the air force, you'd be better checking with your enlistment agency in america for up to date requirements at each level.
L is right though, there is a huge difference when you apply for an officer or commando training instead of typical private-ship in infantry
