Kicker at level 02
After you come out of the armoury and have your carbine and pistol, you will walk past a soldier, he will say permission to open armoury sir! walk over to him and press square, once you have done this follow him till he unlocks a door. go in, you should be in the armoury, if you look around you will get lots of grenades and some other stuff, if you look carefully you should find a sort of gun lying on the floor pick it up, this is the kicker, a tele-kinetic gun.
