Battle field 4: Send c4 down elevators and then wait for the next time the door closes, wait a few seconds then blow it up. Get into a tank battle with someone. When you heavily damage their tank and they bail you destroy theirs. And then move up to where they bailed. If it's somewhere a tank can't go, place c4 on your tank then run away and blow it up when they enter the tank. Be support when your team needs to move up and they refuse to even try. Find the other support guys ammo crate, then throw yours down next to it. Spam smoke grenades in all directions until no one can see a thing and continue to do so until they move up. Shoot other peoples medic bags and ammo crates.
