Whats the GV hangers on your fields for if you're not going to up a tank to kill me? Its not really the death that bothers me, or even the loss of perks when you get right down to it. What bugs me is that I, personally, had nothing to do but hope someone else takes care of it. I'd be fine with rocket attacks. Those are possible and you stand about a 50/50 chance of dodging or avoiding it.
All rockets are perfecly capable of killing any GV in the game. I've killed panthers with HVAR's, Tigers's with 4.5"ers, panzers with the 60lbers, and I've even seen a panther killed with a 110's WGr 21's which are air to air rockets.
