Tips and tricks:

-- You will exit a vehicle where your gun is facing. So If you are, for example, aiming your cannon towards the back of the tank, you will exit at the back of the tank . This is great for people in the 2nd seat of the tank as they can safely exit the tank in any direction and repair it without getting shot --

-- If you play as a recon soldier and you got a MAV, you can use it as an elevator. Simply place your MAV on the ground, exit the flying mode, jump up on top of the MAV and then fly the MAV upwards (not sideways, you will fall off). When you reach a hight you are satisfied with, exit the MAV flying mode. Now you should be up high in the air, standing on the MAV. Quickly jump off the MAV (on to a rooftop for example) as the MAV will quickly start to descend and you might just fall to your death --
