HTK-AS95 WW2 Soviet AFV paint set
Standard colours of Soviet military vehicles during WW2
In a common belief all Soviet AFVs of WW2 wore single-colour olive-green livery. In reality the Soviet Army experimented with camouflaging its vehicles since mid-1930s, which led to first instructions issued already in 1939 (introducing a complex system of four geographical theatres with own camouflage patterns / colours).
However as only three colours were accessible by 1941 - 4BO Green, 6K Dark Brown and 7K Sand - usage of those in 45-55%, 15-30% and 15-30% proportion was finally approved by the end of 1941.
Due to war time economy limitations, till 1943 majority of equipment continued to be finished in one of the greens (4BO, ZK or ZO). Only in 1944-45 use of three-colour camouflage became more common.
