RNC Defense

Escape

RNC Defense is the set of immediate survival actions taken when an opponent on your back is attempting to lock in a rear naked choke. The goal is to prevent the choking arm from securing under the chin and create enough space to begin escaping back control. Timing is critical—defense must begin the moment the choking hand starts to cross the centerline of your neck.

Quick Reference

Key principles

  • · Chin alone is not a defense; you must actively fight the hands with two-on-one grip control on the choking arm.
  • · Keep your elbows tight to your torso to deny space for the choking arm to slide under your chin.
  • · Strip or redirect the choking hand toward your chest rather than pulling it away from your neck.
  • · Turn toward the choking arm side to reduce the angle of attack and begin back escape transitions.
  • · Act immediately—once both hands are locked behind your head, survival odds drop dramatically.

Execution

  1. 1 As soon as the choking arm reaches across, grab the wrist and forearm with both hands and pull it down toward your chest, keeping elbows tight.
  2. 2 Tuck your chin as a secondary barrier but prioritize two-on-one grip fighting to peel or redirect the choking hand below your chin line.
  3. 3 Turn your body toward the choking arm side, angling to get your back toward the mat and your shoulder into the opponent's chest.
  4. 4 Once you have controlled the arm and begun turning, work to get your shoulders to the mat and slide your hips to escape the back position.
  5. 5 Transition to a defensive guard or scramble, completing the escape from back control.

Common mistakes

  • × Relying solely on tucking the chin without hand fighting, which only delays the choke and exposes the jaw to crushing pressure.
  • × Grabbing the opponent's hands with a symmetrical grip (one hand on each of their hands) instead of committing both hands to the primary choking arm.
  • × Turning away from the choking arm, which actually exposes the neck further and helps the attacker finish the choke.
