I think that the security team should have the ACOG sight for the M16A4 and other weapons. When I first played the game, I didn't really get why you could put the ACOG on the A2 and not the A4, as the ACOG is very commonly used on the M16A4. I also feel that the tariq and and M9 should be switched between teams, so that security gets the M9 and insurgents get the tariq. It just seems like a better fit.
