TTsKO (Short for tryokhtsvetnaya kamuflirovannaya odezdha) (Three Colour Camouflage) was a pattern developed in theearly 80's and lasted well into the Russian Federation, seeming to be completely replaced by 1994/5. TTsKO was used mainly by VDV and Naval Infantry units. Modern day Ukraine still uses a modernized variation of TTsKO for their armed forces. Development began sometime in the dark 80's, with a project called "Butan". This development project spawned along with the usual TTsKO also a few other, lesser known patterns. TTsKO saw its first use in the Soviet war in Afghanistan in this conflict it was issued in limited quantities to Officers and Aircrew members. During the First Chechen war TTsKO was still a common sight, mostly among Naval Infantry troops. TTsKO was still marginally used in the Second Chechen war, at least by Naval Infantry and some less fortunate MVD troops. Entering service in 1981, the Soviet tritsvetnaia kamuflirovannaia odezhda (TTsKO) or three-color camouflage uniform (pattern) became one of the most ubiquitous designs in the USSR and the ex-Soviet republics. The colloquial name for this pattern is Бутан or butan (butane), which was the original project name for the camouflage development program. Initially produced as a six-pocket combat uniform for airborne and spetsnaz personnel, the pattern eventually saw production on insulated winter uniforms, aviation uniforms, and special one-piece jumpsuits. The number of intentionally produced color and drawing variations is manifold, with many ex-Soviet republics adopting one or more derivative patterns of their own following the breakup of the Soviet Union. This is probably the most varied of any Soviet-designed camouflage pattern, although sadly its use even in ex-Soviet republics is gradually drawing to a close. Although the main color variants can be divided into green- and -brown dominant, a number of sub-variants have been documented, including pink, tan, oxblood, green/blue, a bi-color variant, and a special muted pattern reputedly issued to reconnaissance personnel. Seen below are a handful of Russian-made variants, with an appropriate descriptive term applied to each.
