Delivering to the troops begun in the beginning of 1942 and they were used to equip the 1. and 2. Armored divisions and the 1. Cavalry division in 1942-43. However, the Turán I was hopelessly outclasses by the Soviet T-34 and it was concluded that a minimum main armament of at least 75mm in caliber was needed.
Such a version of the Turán was on the drawing board as early as 1941 and was originally intended as a support vehicle to the Turán I. Armed with the short-barreled 75mm 41M gun, the new design become known as the Turán II.
The Turán I and II continued to see heavy fighting during 1944 despite their inferiority to Soviet armour of the time. Regardless of this fact, the chassis of the Turán was used in the design of the Zrínyi II Assault gun and was the basis of a design intended to mount the 75mm gun of the German Panther.
