There is a trick you can do in the game, in which you can pull your vehicle inside of someone elses and kill them. Making it possible to take out a tiger with non-offensive vehicles such as the M3's & Jeeps if you know what you're doing.
HOW TO:
Pull up point blank to the target vehicle so when you get in your gun positon you are seeing the inside of the tank, start moving your gun around until you get a big spark accompanied by a loud strange noise. Start hammering that spot for about 3-5 seconds and you will kill the person.
HOW TO DEFEND AGAINST IT:
Stay on the move, cut your engine periodically so you can hear which way they are coming from. More times than not they are going to come at you in something fast so don't try to use your turret on M3's, M16's and Jeeps, use your pintle or hull gun.
So next time you see a Jeep charging you don't laugh, cause you may end up in the tower if you're not carefull.
I realize this is not realistic, nor anything but cheeseball. But it is possible, and is being used alot by the few people who have found out about.
