We found this photo in a forum a few days ago and while we hate to admit it, we don’t know what this is. Obviously these are US built M60 tanks. Since there is only a slot in the add on armor on the right side of the turret, we assume this is an M60A3 (the A3 has the laser range finder in the right side of the turret, whereas the earlier versions use both left and right blisters for the stereoscopic range finder). Other than that, we have to admit we have no idea what this M60 variant may be. Anyone know the answer?
