TRUCK POSITION

The truck position is the leg-entanglement configuration related to back control in which the attacker is perpendicular underneath the opponent, with both legs trapping one of the opponent's legs in a figure-four-like wrap. The position emerges naturally from back control when the opponent rolls forward to escape; instead of releasing, the attacker rotates underneath and ends up in the truck with one of the opponent's legs trapped between their own. The position scores no IBJJF points but is a primary submission hub in modern no-gi grappling.

The truck was popularized by Eddie Bravo and the 10th Planet system in the late 2000s as the entry point to the twister submission, the calf slicer, and various back-take chains. The position's nickname 4-11 refers to its appearance: the attacker's body forms a numeral-4 shape with the trapped leg, while the perpendicular alignment to the opponent creates the geometric configuration the name describes. From the truck the primary attacks are the twister (Eddie Bravo's signature spinal lock), the calf slicer on the trapped leg, the kneebar via figure-four extension, the heel hook in no-gi rulesets that permit it, and direct transition to back control by rotating underneath.

The technique demands flexibility and a willingness to operate from a position where conventional top-position vocabulary does not apply — the attacker is below the opponent in a way that resembles guard, but the configuration is offensive rather than defensive. Modern competitors like Geo Martinez, Richie Martinez, and the 10th Planet lineage have built entire competitive careers on the truck position. Defensively the truck is escaped by sprawling the trapped leg backward to release the figure-four, by spinning to face the attacker before submissions develop, or by attacking the attacker's exposed back during the perpendicular alignment.
