1. ZiS–30. Source: Russian Military Zone. 101 were built from modified Komsomolets tractors from 21 September to 15 October 1941. [up]

2. SU–76P. Source: Russian Military Zone. This was the first of many vehicles to be called SU–76 until 1943, when it became SU–76P to avoid confusion with later vehicles which were also called SU–76. It was built in Leningrad during the grim days of the seige and was a hasty combination of a 76mm regimental field gun obr.1927 mounted on a T–26 chassis. There was no protection for the crew other than the gun’s shield. I have assumed the T–26 chassis was an obr.1933 to 1938 because these were the most common and the photograph shows a straight sided chassis rather than the sloped sides of the later versions of the T–26.

3. SU–76. Source: Russian Military Zone. The naming of the SU–76 series is very confusing. There were two similar vehicle designs, SU–12 and SU–15, each of which became modernised gaining the ‘M’ designation. Although they differed in several ways (such as automotive components) their armour was very similar, the main difference being that the SU–12 was completely enclosed while the SU–15 had an open superstructure rear and top. The first SU–76 (factory designation SU–12) was produced from January to March 1943. Production was halted because mechanical difficulties with the engine and transmission led to frequent vehicle breakdowns. A modernised version SU–76M (factory designation SU–12M) was produced from June 1943. A further improved version was produced from October 1943, which was given the factory designation of SU–15 or SU–15M but was officially called either SU–76 or SU–76M, the same names as the earlier versions. This last version was the only one with an open rear and top. I have no information on the armour for these areas on the earlier versions. [up]

4. SU–122. Source: Russian Military Zone and Red Steel. The SU–122 was originally named the SU–35. Production ceased Summer 44. There are conflicting armour thicknesses for the SU–122 in the references, however as the SU–122 chassis is based on the T–34 this has been used instead. The value for the SU–122 mantle might be different because of the different armament so it is designated it with a “?”. The lower front hull angle is variously given as 53°, 55° and 60°, with the latter being the most common and backed up by actual tests on Soviet vehicles, so 60° has been used for all T–34 based vehicles.

5. SU–152. Source: Russian Military Zone and Red Steel. The name was changed from KV–14 to SU–152 on 14 Feb 43. The armour scheme on the Russian Military Zone was missing the angle for the lower front and the upper rear armour, so these were taken from the KV–1S armour scheme as the chassis for the SU–152 was based on the KV–1S chassis.
