Your light machine gun doesn't do much more damage than other guns but you have quite a bit more ammo per magazine. Revive dead teammates with your paddles (they appear as lightning bolts on the map and your HUD). Once it's locked, it's locked, but the next time you shoot you'll need to lock again. You do not need to stay aiming until it hits. You can even shoot straight in the air to curve it around buildings and terrain. Once it stop blinking, you have about two seconds to shoot. Once it's on the vehicle, look down the sight of your RPG at the red blinking square in the direction of the beacon.

Any class can use the tracer dart, but here's how to lock onto it.

The CG does less damage but the rocket travels faster and has a wider damage radius. Shoot vehicles with the RPG-7, shoot soldiers with the Carl-Gustav.

Engineer - Repair friendly vehicles, blow up enemy vehicles.

Shoot your grenade launcher at bunched up enemies. Long distance works well too but that's best effective on defense.

Assault - Drop ammo packs near teammates.

These rules bend a lot but you'll learn that with experience.

Play to the strengths of the class you're playing.
