Rubber guard

The rubber guard (sometimes referred to as Mission Control) is a Brazilian Jiu-jitsu technique, which involves the practitioner ‘breaking down’ the opponent into the rubber guard, while maintaining a high level of control. It utilizes extensive flexibility to control the opponent with one arm and one leg. The opposite arm in turn is free to attempt submissions, sweeps or to strike the trapped head of the opponent.
Rubber guard, as well as other innovative guard moves, is attributed to Eddie Bravo who adopted it as a staple technique of his 10th Planet Jiu-Jitsu. Modern variations of the Rubber guard have been created in the gi, with the Gubber guard being used by Keenan Cornelius. This is a similar set up to the Rubber guard but involves the use of the lapel to control the opponent's posture.
