@Garde de Paris: The Soviets used 4 different 76mm Divisional guns in WW2.
There's the M1902/30, a modernized version of the gun used in WW1. Longer barrel (L30 to L40), much greater elevation (17 to 37deg), and a new AP round (59mm at 1000m). link
There's the M1936 (F-22), which had a big split-trail carriage and limited AA capability with a 75deg max elevation(!). link This gun was just way too complex, and was slow to produce due to all the changes getting made to address problems. Only about 3000 guns were made from 1936 to 1939 (a big problem when every Russian Division had twenty 76mm guns).
There's the M1939 (F-22 USV), which also had a big split-trail carriage but didn't have the elevation for AA firing like the M1936 did (max of 45deg elevation). en.wikipedia.org/wiki/F-22USV There were about 1200 produced in 1939-1940, then production stopped due to having enough 76mm guns. With the German invasion in 1941, production resumed and there were 2600 made in the remainder of 1941 and another 6000 in 1942. In 1943, production shifted to the ZiS-3, which had been designed by the same engineer as the USV.
The M1942 (ZiS-3) is the F22USV barrel mounted on the light ZiS-2 carriage, with a muzzle brake added. link Over 103,000 ZiS-3s were made from 1942 to 1945.
All of the various guns used the same ammunition.
This is a ZiS-3, the smallest and lightest of the 76mm guns.
been building and painting his own army for Flames of War for a while now.
