Hi guys small update on my M1A3C visual study. I made two distinct LOS thickness estimations, one with reference to the 66mm smoke grenade launcher (not a perfect solution, since because of picture perspective, the grenade launchers appear as bigger than they actually are) which yielded a LOS increase of aprox. 287mm over the older M1A2 turret. The second estimation, assuming an LOS thickness for the M1A2 turret thickness of 860mm resulted in an estimated 973mm for M1A2C turret. This second solution, IMO, is more trustworthy but there is some margin of error since it´s not that easy to estimat
