Rules to live by:
1.If it moves, shoot it.
2.If it doesn't move, poke it with your turret and then shoot it.
3.When in doubt -- empty your magazine!
4.If your attack is going really well, it's an ambush.
5.No plan survives the first contact with the enemy.
6.Five second bombs blowup in three seconds.
7.Try to look unimportant. The enemy may be low on ammo.
8.Teamwork is essential -- it gives the enemy other people to shoot at.
9.Incoming fire has right of way.
