Leg-behind-neck guard
Also known as Rubber Guard — the canonical term used on this site.
Training background: Descriptive term based on the defining structural feature
Descriptive — leg-over-shoulder rubber-guard configuration
Leg-behind-neck guard is the descriptive name for the rubber guard — flagging the leg-over-shoulder and leg-behind-the-neck geometry that defines the position’s posture-breaking mechanism.
Etymology. “Leg-behind-neck” specifies the leg position relative to the opponent’s head; “guard” attaches the position-family. The compound predominates in instructional vocabulary that prefers anatomical-precision description over the “rubber” metaphor.
Mechanics. The leg-behind-neck configuration breaks the opponent’s posture forward and down — the bottom player can attack from the broken-posture state with omoplatas, gogoplatas, triangles, and other submission setups.
Cross-reference. “Mission control” is the 10th Planet system name. Full mechanical coverage on Rubber Guard.
