Tom Clancy's Ghost Recon/Gameplay

A few golden rules of this game:
 * 1) The AI knows exactly where you are and will begin to zero in on your position as soon as the shooting starts.
 * 2) Don't move and shoot at the same time.
 * 3) Don't "spray and pray". Try to use single shots.
 * 4) Be aggressive.
 * 5) The SA80 is the best gun in the game. After that comes the OCW due to the full-on artillery barrage you can call down with the grenade lugger. In fact, it's worth having at least one OCW on your team, as it can buy you some time in an emergency. If you hit an area with a full clip of OCW grenades, the AI will seek cover, giving you a chance to take more solid cover.
