The battle in suburbs of Brandenburg. Spring 1945.
By June 1945, the total production of the SU-76 reached 14,292 - approximately 60% of the total volume of all self-propelled guns produced during the war. It was manufactured in the following factories: Factory #30 in Kirov, Factory #40 in Mytishchi, and the GAZ Factory in Gorkij.
The updated version was delivered to the Army on time, but it left a questionable impression on its crews, and received nicknames such as "Suka" (Bitch) or "Golozhopij Ferdinant" (Naked Ass Ferdinand). Tankers who never fought in the SU-76, but who had judged it from the outside gave such unpleasant nicknames. Tankers who fought in the SU-76 called it "Colombina," which was a somewhat affectionate name. The first negative impressions of the vehicle were formed when they were pressed into service as tanks. The first SU-76s were sent to mixed self-propelled artillery regiments and in the summer of 1943, each unit was supposed to have 21 vehicles (four batteries of five vehicles each and one commander's SU-76). Only with time came the realization that the main task of the SU-76 should be close support of the infantry. The task of fighting enemy tanks was left to more powerful artillery systems based on the chassis of the T-34 and the IS-2 tanks. As a result, by the end of 1944, SU-76s were placed into light self-propelled artillery batteries of sixteen vehicles each, which were then part of regular infantry divisions.
Naturally, among the sixty shots that a SU-76 carried, some were armor-piercing. However, its main advantages were its low profile, high mobility, and low ground pressure (0.545 kg/cm2) which allowed it to operate in the marshy and forested areas which had poor ground conditions, in close cooperation with the attacking infantry, and in firing directly at pillboxes and fortified buildings.
The SU-76 "Smelij". Transbaikal Front. August 1945.
Further use of the vehicle in street battles at the end of the war uncovered another disadvantage of the system - the semi-open superstructure of the vehicle, which was roomy and excellent for crew movement, became a mass grave for its crew in case of an infantry grenade explosion. On the other hand, the opened compartment made all types of high-explosive anti-tank (HEAT) ammunition (including weapons such as the "Panzerfaust," the "Faustpatron," and the "Panzerschreck") totally ineffective.
The first batch of SU-76s (25 vehicles) was delivered by January 1st, 1943, and was sent to the self-propelled artillery training school. At the end of January, the first two mixed self-propelled artillery regiments (the 1433rd and the 1434th) were sent to the Volkhov front to assist in the relief of Leningrad, and in March 1943, two more regiments (the 1485th and the 1487th) were formed, and fought on the Western front.
In 1943, a light self-propelled artillery regiment had a full complement of 21 SU-76M. At the end of 1944 to the beginning of 1945, seventy batteries of self-propelled artillery (consisting of sixteen vehicles in each battery) were formed and attached to rifle divisions. In the first half of 1944, light self-propelled artillery brigades of the Reserve of High Command (RGK) were formed, and consisted of sixty SU-76M and five T-70s each.
By the end of the war, the Red Army had 119 light self-propelled artillery regiments and seven self-propelled artillery brigades. The Polish army received 130 SU-76M. The SU-76M was used in the design of the ZSU-37 self-propelled anti-aircraft gun, which was armed with a 37 mm automatic anti-aircraft gun. It was manufactured at Factory #40 in Mytishchi, but it did not see action in World War Two. A total of 75 units were manufactured in 1945 to 1946.
The active service of the SU-76M did not end with the Second World War. The Soviet Army continued to use it through the early 1950's. The 130 vehicles given to the Polish Army were also taken out of service in the mid 1950's. A few dozen SU-76M that North Korea received saw action in the Korean war from which almost none survived.
The story of SU-76 would not be complete without an account of further attempts to modernise it. In December 1943, a SU-74B tank destroyer with a ZIS-2 anti-tank gun was tested, as was a GAZ-75 with an 85 mm D-5-S85A gun in 1944. It had the same 85 mm gun as the SU-85, but it had half its weight and its frontal armor was twice as thick (the SU-85 had 45 mm, and the GAZ-75 had 90 mm of frontal armor). None of those designs ever entered mass production, the main reason being a reluctance to disrupt the production of existing designs for the benefit of only minor improvements, as in the case of new engines, or to completely rework the manufacturing process for a new model.
