I swear there was a topic dedicated solely to anti-tank rifles somewhere on the forum, but the search option isn't pulling anything up, so bear with me please! We all know that by 1942 anti-tank rifles were virtually useless, but did this stop them from being used nevertheless? Several such weapons were quite powerful (the Soviet PTRS/PTRD 14.5x114mm round could penetrate 30-40mm of armour at 100m). This made them useful against light tanks and other lightly armoured vehicles and even the possiblity of damaging a heavy tank's treads or optics (and quite possibly penetrating side/rear armour). I have several questions concerning anti-tank rifles; were they still issued to troops after the weapons' flaws were realized, and if they were, how were they incorporated into troop units- were specialized, anti-tank infantry companies given the rifles, or were they implented into squads or platoons or something totally different? Also, during the Second World War, were anti-tank rifles fitted into other specialized roles, such as long-range sniping or anti-boat duty?
