I just had two games in a row where I got multiple direct hits on T-55 variant tanks, and I didn’t even get a hit notification. I was using the M60A2, with a laser rangefinder, as well as the M901 ITV. The 152 mm HEAT shells, the Shillelagh missiles, and the I-TOWs all seemed to phase through the turret and hull of the T-55 variants. Meanwhile, the spawn-camping T-55 was able to return fire without issue. I don’t know if this is a HEAT/ATGM based issue or a T-55 specific issue. I didn’t have issues with the XM803 at all when using ATGMs.
