When you choose the tanker class to play the game, you will be deployed inside the tanker. You can spawn into a Mark V, FT7 or an A7V tank. You will have an amazing firepower but you are driving a big slow tank. You will be the one that is in control of the vehicle, but allies can jump in and use multiple guns on the tanker to give you even more firepower. Working together with your teammates is the best course of action while playing this class.
