Introduced around 2004, the SS-leto (SS Summer) pattern is heavily influenced by WW2 German oakleaf pattern camouflage. The style of uniform is called Partizan. The summer version of the pattern features loam, dark brown & sandy yellow shapes on a moss green background, and reverses to a subdued version. An autumn version incorporates black, loam, dark brown, ochre & moss green shapes on a sandy background, and also reverses to a subdued version of the pattern. Both patterns are popular with Russian special operations troops in the VSR and MVD, as well as the Spetsgruppa Al'fa of the FSB, who were the initial users. A reversible variation of this uniform, the Partizan-M incorporates a spring coloration (approximating the shades of the original WW2 German pattern), with autumn colorations having more subdued tones.
