The first mass-produced Soviet camouflage uniform was the makirovochnyi kamuflirovannyi kostium or MKK, printed with large reddish-brown amoeba shapes on a light green or khaki background. Introduced in 1938, the MKK (also issued as a one-pieced coverall or makirovochnyi kombinezon - MK) was in service with engineers, snipers, airborne forces, forward artillery observers and reconnaissance units throughout the Second World War. Colouration of the pattern varied depending on the factory that produced it, and there is sufficient evidence to suggest that specific colour variants were produced for particular seasons or types of climate. Uniforms in this pattern continued in service sporadically for the next couple of decades, and even longer with reservists and cadets. This camouflage design is often called Soviet "amoeba" pattern.
