Oh? I hit a M4A4 76W at LEAST 6 times with a Tiger, and 2 of those times, they just bounced right off. The other 4 showed that tall tale sign of a solid hit, but he wouldn't die (I didn't even track or turret him). What makes it more interesting is, there was another guy firing on the same tank, and was landing hits to his side. He mentioned that he hit him about 8 times himself. I forgot what he was using but I think it was a Panzer. For sure my Tiger should've killed him. I was about 800 - 1k away from the M4A3 76W. The good side to it is, his shots were just bouncing off my Tiger. But me thinks that he shouldn't have survived the first hit, let alone the 6th OR the flank shots from a Panzer.
They will need to look into the M4A3 75 as well. There have been times where I would put a near direct flank hit to one, and it would just bounce off. Of course, I was using a A3 75 myself, so maybe it's the gun? Range on the last one I hit was about 1k-ish, give or take 100 yards. I havn't had the chance to do a flank shot on the A3 75 in anything but a A3 75. But it's possible that if the 76W is like this, the A3 75 could be like this as well. I have noticed that she can take a punishing before going down. Do enjoy that tank though.
I consider it one ell of a B-day present, since that's when they were "released".
