Last time I checked, Hitech was CEO of the company, not Pyro. If HT says there will be GV's ("engage in air, LAND, or sea combat"), then there will be GV's. If we had more of them, then they would start to rival AC in base captures, and usuage IMO.
About the only thing that tops GV's and AC in importance is working the kinks out of what we have now (we just got some new stuff). But since the main holes in the AC line up are EW, Jap, Italian, and, to a lesser extent, Russian planes and non US bombers, GV's should get a turn.
We have 5 tanks, to the 50 or so fighters we have. We have no tank destroyers, no panther, no KV tanks, and no british tanks (firefly uses a british GUN, the tank itself is US).
