Poor opposition then. Two rpg's to the AA and it's dust . No way should he have been allowed to get 65-3. In a tank with a good gunner protecting you then yes. Unless of course your guy had two engineers behind him at all times repairing him?
Considering most AA vehicles sit way out of range of infantry....unless it's one of those morons trying to use it as a tank.
Actually unless they changed it in the patch, the grenade launcher is pretty decent against armour.And in rush, the only vehicle available to the americans is the Amtrack. Which simply doesn't have the fire power with that grenade launcher to take out the mobile AA.
