Самбо is a Russian martial art and combat sport that combines elements of judo and wrestling. It was developed in the early 20th century to improve the hand-to-hand combat skills of the Soviet military. The name "самбо" is an acronym for "self-defense without weapons" in Russian. The sport emphasizes throws, grappling, and ground fighting techniques. Competitors wear a jacket called a kimono and use a belt to secure it. Самбо has two main styles: sport sambo, which focuses on competition, and combat sambo, which includes striking techniques. It is practiced worldwide and has gained popularity in various martial arts communities.
