EMF, study some squad size military tactics. You will be amazed how much it will help your game. Remember it is a lot harder to hit a moving target. If you are under fire...shoot.....move.....shoot....move. Move in different directions....that way they can't lead you. If someone has you in their sights....duck...that takes you out of their sights....then MOVE. It confuses people to have you in their sights one second and gone the next.
