The STABO (STAbilized BOdy) extraction harness was a device which allowed military personnel to be rescued (by helicopter) from field locations which prevented the conventional landing and boarding of a helicopter. It was designed and developed by U.S. Army Special Forces personnel stationed in Vietnam during the Vietnam War, and became a widely used and highly successful extraction device employed during the Vietnam War.
The STABO extraction harness was far more secure, safe, and comfortable than the McGuire rig, and most importantly allowed the unrestricted use of the operator's hands to operate any weaponry during the frequently 'hot' extractions from a combat LZ/PZ (Landing Zone/Pickup Zone). Further, the rig was equally effective if the operator was wounded, or unconscious.
Many were fused together in conjunction with WW2/Korean War BAR belts as webbing suspension by US Special Forces (LRRP / MACV-SOG) operators who used BAR belts for their larger carrying capacity compared to M1956 webbing.
