This is a clip of the match between Fedor Emelianenko (21-1) vs Aleksander Emelianenko (6-1). These guys are among the top in the MMA world and this is an older clip of them facing off in a SAMBO competition. SAMBO is a Russian martial art, not a Caribbean dance, that involves a gi jacket and many joint locks, submission grappling.
