As the Groundwire

 * Don't even try to bother using this tank. It has a slower reload than the Submachine, for absolutely nothing. And how did it get one million as its high score while its just so weak?

Against the Groundwire

 * Any tank can beat the Groundwire, but if you want to rub it in, go for the Blaster branch, especially the super powered Twisted Hybrid, Dual Blaster, and the Planter because Groundwires are Blaster's food.
