Combat Sambo was developed for the Russian military, and resembles mixed martial arts. Unlike sport Sambo which prohibits chokes, various joint locks, and strikes, Combat Sambo allows striking chokes, and wide variety of arm and leg locks. Fighters wear jackets as in sport sambo, plus shin, hand, and head protection.
Head butts are among the prohibited techniques, but that did not stop this competitor in a recent competition in Russia.
