The Zrínyi assault gun was used to fight against the Soviets on the Eastern Front and in the defence of Hungary and it was quite a successful vehicle.

The Zrínyi's development process started in 1942; after the Hungarian delegation had the chance to witness the success of the StuG III Ausf.

[2] Following the success of assault guns on the Eastern Front, the situation required the fastest way possible to start the production of a vehicle of the same role.

The engineers at the Manfréd Weiss Works decided to use the base of the Turán tank as it was a proven, solid chassis already in use in the Hungarian army.
