The uniforms worn by the ROTC cadets is the Army Combat Uniform or ACU, which was not introduced until 2005. Since the film is supposed to be set in 1995, the ROTC cadets should be wearing the Battle Dress Uniform or BDU.
During the war games, there is a scene where three camouflage clad girls are standing in a lake enticing a group of soldiers to come skinny dipping with them. The girls remove their shirts, one of which is now bare breasted, the other two having on a black and flesh colored bra, respectively. The soldiers are then shown running into the water and frolicking with the girls, who are all shirtless, and are not holding any of their removed clothing. In a following quick cut distant shot, the three girls are all shown once again with their tops back on, without having had any time to pick up their shirts and get redressed.
