Jocko Willink, retired commander of the Navy SEAL Team Three Task Unit Bruiser, decorated Iraq War veteran, and all-around brutal dude, remembers the first time he encountered Jiu Jitsu back in 1992. He got the snot knocked out of him.
A SEAL master chief introduced Willink to the rear naked choke, a staple of the Jiu Jitsu repertoire, by taking him and a handful of other strapping young men to the dirt like it was nothing. That day launched Willink's love for the sport.
