Wut? a single assault CAN'T kill a tank at all unless the tanker screws up royally - let alone "quite quick".
Glad OP doesn't work 4 dice. There are enough AA wh*res as it is
BTW im sick and tired of the nerf brigade. So we had MH, hellriegel, AA, tanks and next up = planes? Wonder what they gonna cry about next, it's getting old
