In 1944 each divisionís artillery had a battery of anti-tank guns equipped with TAC 43 Reşiţa 75mm anti-tank guns.This modern weapon combined aspects of the German PaK40 and the Soviet ZIS-3 anti-tank guns to create an effective weapon capable of destroying most enemy tanks.
The Reşiţa 75mm gun came out of experiments with the M1936 Vickers/Reşiţa 75mm anti-aircraft gun. In the end the carriage and weight of the anti-aircraft gun proved too big an obstacle to continue with this as an anti-tank weapon. The Reşiţa factory went about designing a dedicated heavy anti-tank gun. It was also decided to make it a multi-purpose weapon doubling as a field gun like the Soviet 76.2mm ZIS-3 gun.
