We ran up on a V-base in a flight of 7 or 8 jugs and after it was all said and done all hangars were down, and all the wirbles were dead and the only remaining one was turreted.
all the jugs were out of ord by now and just had guns.
long story short then wirble drove over and parked at the map room, soaked up around 18,000 5 cal rounds plus some 20mm from a spitty that was around all the aircraft in the area completely emptied their guns on it, and it just sat there, we figured MAYBE since it had been hit so much that the hull gun was dead, so we rolled in troops.. nope.. picked em all off, and jsut remained sitting there till the first hangar popped and of course came the wirble flood and it was over (we had ord on the way but it was too late, was a long flight)
thats the only beef I have with the wirble, it cannot be tracked and the hull gun cannot be killed with MG fire.. no matter from what angle or how much of it.. granted its a tough chassis, and you shouldn't be able to pop one with a couple rounds of 50 cal.. on the extreme other hand though it shouldn't be literally immune to over 15,000 hits either... you strafe anything from that era with that much 50 cal its going to be out of commission.. the tracks would be for sure.
that and the only place you will see a M16 now is.. nowhere.
