IDF HAT does sometimes go through an entire vehicle and can actually hit another one behind it dealing damage to both.
Also it deals randomly more damage than it should: it can sometimes onehit destroy a tank on the side as well as leave it at 20% HP when shooting on its front.
Distance seems to affect this since it happened at close range (50 mts) but failed to reproduce at 200 mts.
Tested on local non-COOP server on Bijar map STD against both Merkava and T72-S tanks.
