CC Ripsnort, I do that (move just a hair to change impact point) but it doesn't make any difference.
Ever once in a while I can kill an M3 or an FP with 3-5 hits, but usually it is well over 10 rounds to kill it. I am also aware of the vehicle supply thing, but if the enemy gv took on supplies, he would stop smoking and it would be obvious what he is doing...but I am talking cases where it is clear there are no supplies.
Here's a good one...just about 30 mins ago we had an M16 roll onto one of our fields, it was getting hit by field ack, 3-4 of our own gvs at point blank range, bombs from above and it sat there in the middle of the runway for about 5 minutes just shooting the field to pieces. It finally died, but I was unable to find out who it was.
IMO, vehicles are hosed in AH and need some serious reworking...they used to be loads of fun, now it is more frustrating than anything...shame too, I love gv battles...nice distraction from constant furballing.
