On any map that has heavy vehicles, put a Scorpion tank in it. Have a shotgun out. Go on the Scorpion tank and stand on the middle of the nose. You can stand in the middle of the gun. Fire your shotgun at about the timing which a Scorpion tank cannon would fire. Note: This works best when you are using a brown or sage colored Spartan. Opponents should see you, and if they check out the tank, blow them to bits.
