Control arm choke
Also known as Short Choke — the canonical term used on this site.
Training background: Refers to the arm role in the seatbelt that becomes the choking arm
Descriptive — choke using the seatbelt's control arm
Control arm choke is the descriptive name for the short choke — flagging the configuration where the choking arm is the same arm that was previously the seatbelt’s control arm, with the choke completing from that arm-already-in-position state.
Etymology. “Control arm” references the seatbelt grip’s “control” arm — the arm that wraps over the shoulder rather than under the armpit. When that arm becomes the choking arm, the resulting short-choke geometry differs from a standard rear naked choke entry. “Choke” attaches the category. The label appears in instructional contexts that teach the choke as the natural progression from the seatbelt grip.
Mechanics. The configuration uses the seatbelt-positioned arm to close the strangle directly from the back-control grip — no transition through a fresh wrap is required, which is the technique’s efficiency advantage when it’s available.
Cross-reference. “Short choke” is the canonical site label; “under-chin choke” emphasises the chin-position geometry. Full mechanical coverage on Short Choke.
