On 8 September 1946, Moscow celebrated the Day of Tankmen for the first time. The holiday was established not only in honour of the troops – against the backdrop of the intensifying Cold War and the lack of nuclear weapons, Joseph Stalin paid particular attention to every opportunity to demonstrate the power and combat readiness of the Soviet Army.

A secret decree by Lieutenant-General Kuzma Sinilov, the military commandant of Moscow, dated 5 September 1946 ordered a reconnaissance group of motorbikes and armoured personnel carriers to be sent through Red Square and the streets of the capital in combat formation, a leading squad of tanks, anti-aircraft guns, self-propelled guns, a battalion of motorised infantry, a tank regiment, a battalion of SU-152 self-propelled guns, an anti-aircraft artillery air defence division, an armoured personnel carrier battalion, a "T-34" tank regiment, an IS-3 tank regiment, and other forces. During the movement of tanks through Red Square, a 24-gun salute was fired in the Kremlin. The tank parade was received personally by Stalin, donning the uniform of the generalissimo.

The military celebrations would become an occasion to showcase the military strength of the USSR for a long time to come.
