Use a tank on Suez or Verdun ( conquest ) don´t try to cap flags on your own try to think of your big tube as a sniperrifle, keep your distance at all times unless alot of friendly creatures decide to rush in then you can move in a bit.
Oh and don´t have a gunner you will use that seat better on your own.
