Turtle armbar defence
Also known as Rolling Armbar Escape — the canonical term used on this site.
Descriptive — armbar hunted from the turtle position
Turtle armbar defence names the rolling armbar by where it is hunted from, marking it as one of the arm attacks that live in the turtle rather than in guard or mount.
Etymology. The positional label is the practical one for a defender, because the turtle is where the counter-habits have to be installed. Naming the position rather than the finish puts the emphasis where the defence actually happens.
Mechanics. Turtle defence against arm attacks is about post discipline. Long posts offer a limb that can be fed back through the defender’s own plane; short posts with elbows connected to the ribs give the attacker nothing to collect. The escape is then a matter of recovering the elbow past their knee line and sitting out before the roll begins.
Cross-reference. “Roll-through armbar escape” is the descriptive name. Full escape coverage on Rolling Armbar Escape.
