As the Groundwire

 * Don't even try to bother using this tank. It has a slower reload than the Submachine, for absolutely nothing.

 * 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.
