As the Knocker
The Knocker provides ample firepower while having protection on its back as well.
 * Use your array of guns to overpower and outpenetrate weaker tanks like snipers or drone tanks.
 * Thanks to the Knocker's rear guns, you do not suffer any backwards recoil when firing and moving forward.

Against the Knocker

 * The Knocker's lack of side guns and low reload makes it somewhat vulnerable from those angles before they can turn and cover them.
 * The Heavy Twin's bullets deal a lot of damage and can take out unprepared players.
