Some defintiions from the Wikipedia:

"Sambo (Russian: са́мбо, pronounced [ˈsambə]) is a Russian martial art, an internationally practiced combat sport,[2][3] and a recognized style of amateur wrestling included by UWW in the World Wrestling Championships along with Greco-Roman wrestling and freestyle wrestling.[4][5]

It originated in the Russian SFSR in the Soviet Union. The word sambo is an acronym of the romanization samozashchita bez oruzhiya (Russian: самозащита без оружия), which literally translates to 'self-defence without weapons'.[6] The correct, official English spelling, approved by USA Wrestling and the United States Olympic & Paralympic Committee, is SAMBO.[1]

Sambo is relatively modern since its development began in the early 1920s by the Soviet NKVD and Red Army to improve hand-to-hand combat abilities of the servicemen.[2] It was intended to be a merger of the most effective techniques of other martial arts.

The pioneers of sambo were Viktor Spiridonov and Vasili Oshchepkov. Oshchepkov spent several years living in Japan and training in Judo under its founder Kano Jigoro.[7] Oshchepkov died in prison as a result of the Great Purge after being accused of being a Japanese spy.[8]

Spiridonov and Oshchepkov independently developed two different styles, which eventually cross-pollinated and became what is known as sambo. Compared to Oshchepkov's system, called "free wrestling" in Russia (known in the West as catch-as-catch-can wrestling or simply catch wrestling), Spiridonov's style was softer and less brutal. It was also less strength-dependent, which in large part was due to injuries Spiridonov sustained during World War I.[9]

Anatoly Kharlampiev, a student of Vasili Oshchepkov, is also considered a founder of sambo. In 1938, it was recognized as an official sport by the USSR All-Union Sports Committee."

"Combat sambo (Russian: Боевое Самбо, romanized: Boyevoye Sambo). Utilized and developed for the military, combat sambo resembles modern mixed martial arts, including forms of striking and grappling. Combat sambo allows regular punches, kicks, elbows, and knees, as well as soccer kicks, headbutts and groin strikes, in addition to throws, holds, chokes and locks, except for a standing or flying wristbar.[12] The chief distinction from Brazilian jiu-jitsu (BJJ), apart from striking techniques, is that combat sambo rules and regulations do not permit a one-sided resort to ground fighting without throws or other combative maneuvers (i.e., by simply sitting down and continuing from the ground without touching his opponent that BJJ allows). In terms of aliveness, combat sambo surpasses ARB by design, though both were designed for combat situations only. Competitors wear jackets as in sport sambo, but also hand protection and sometimes shin protection and headgear. The first FIAS World Combat Sambo Championships were held in 2001. The World Combat Sambo Federation, based in Russia, also sanctions international combat sambo events."
