Agency administrators who are responsible for defensive tactics programs or writing use of force policy need to have a strong understanding of terms and definitions. We’ve helped define some of the common jiu-jitsu terms and positions that may help explain an officer’s action in a report. We will continue to add to this list as requested/needed.
Knee Ride: Maintaining a constant point of contact on top of a suspect with the officer’s knee or shin. A knee ride is not a strike. This contact is meant as a control measure using pressure to limit a suspect’s ability to move or escape. Officer’s should try to avoid placing a knee directly on a suspect’s spine or throat. The jiu-jitsu term for this position is a ‘Knee on Stomach’.
Shin Staple: Using the officer’s shin to pin a suspect’s limb to the ground. As the shin is in contact with the suspect, the officer’s foot and knee are both in contact with the ground, thus producing a “staple” effect.
Shrimping: Elevating hips off the ground with the purpose of creating lateral movement. Typically the shoulder becomes the pivot point as the hips move. The drive of the movement comes from a push from the legs in conjunction with using core strength.
Bridging: Elevating hips off the ground with the purpose of creating vertical movement. Contact with the ground is maintained with the shoulder and the feet. Bridging should not be done on the neck for safety reasons.
