SOG’S HALO JUMPS

Full Story 

The McGuire Rig

Named after its inventor, Sgt Maj Charles T.McGuire, a member of project Delta circa 1964-1965. The McGuire rig was a device for
extracting up to 3 patrol members in one go from area’s in the jungle that were inaccessible, or where enemy fire prevented a normal helicopter extraction.  The rig was basically a 2in wide webbing sling, which was attached to the end of a rope, which was in turn lowered from a hovering helicopter. The individual(s) would then place the web sling around their buttocks (sitting in it), and slip their hands through the wrist loops that were attached to the sling. These would tighten up to prevent the person from falling as he was hoisted away by the helicopter. The main limitations with the McGuire rig were that it had to be fitted while standing upright, and that the users hands were NOT free to untangle themselves, fire a weapon, or use a radio. The rig was also uncomfortable and impaired the blood circulation, for these reasons it was normally used only in dire emergency situations which involved short distances of flight.

HANSON RIG

Hanson RIg

VIETNAM HANSON RIG EXTRACTION HARNESSThese are made in very limited quantitiesHISTORY: Developed by FOB-2 One-Zero Bill Hanson. This method of extraction preceded the STABO Harness. The Hanson Rig replaced the McGuire Rig as a safer, more reliable method of Helo extraction. These were typically folded over then taped and secured to the equipment belt or suspenders with a carabiner until extraction was imminent. It was worn for the full duration of the combat operation, in which to allow for rapid extraction by the rope (“strings”) method, if a conventional helicopter LZ could not be quickly established (which was frequently experienced in South East Asia, as reconnaissance teams were operating deep in heavily forested enemy territory).

STABO RIG

The STABO rig:
A direct descendant of the McGuire rig and was first demonstrated by the Special Forces MACV RECONDO school on the 1st of October 1968. The STABO rig was a more efficient extraction harness.  The new rig was developed by Maj. Robert Stevens, Cpt. John Knabb, and Sfc Cliff Roberts, all of whom were instructors at the Nha Trang RECONDO school. This new extraction harness was called the STABO rig, a name derived from the initials of its creators. The first test rigs were locally produced, when these were deemed satisfactory the 5th SFG put in a priority request for 1000 rigs on the 30th of June 1969.  The STABO rig was made from nylon webbing and resembled a parachute harness, and the infantry mans standard load bearing equipment.  The main lift harness straps formed an “X” across the wearers back, the leg straps were kept secured rolled up with elastic bands, in order to stop them from dangling loose. These would only be buckled up via metal “D” rings under the wearers crotch when he was to be extracted. The harness replaced the normal pistol belt suspenders. The pistol belt itself was threaded through the loops in the harness and allowed various items (waterbottle, ammo pouches, etc) to be attached to it in the normal way.  The Army dragged its feet here a bit by instituting a long and drawn out state-side series of safety tests which were not completed until 31st of March 1970. In the meantime Special Forces had to rely on a limited supply of approx 500 STABO rigs. These had been produced by the 2nd logistical command on Okinawa and purchased through the counterinsugency support office. Eventually regular Army funds became available, and Natick labs began procurement procedures.
An overall improvement over the McGuire rig, and a much safer means of achieving a helicopter extraction (although this method of extraction could still give even the toughest “Ombre” the “pucker factor” big time!), the STABO rig was a good piece of kit. It could be used to extract a man who was unconscious, and if not unconscious would permit the individual to still fire his weapon or use a radio if needed.
From the 16th of October to the 31st of December 1970 approx 3,300 STABO rigs were sent to the 5th SFG and MACV-SOG in Vietnam, and to the 46th SF Co in Thailand.  

Sabo Rig

STABO Rope

The STABO rig was far more secure, safe and comfortable than the McGuire rig, and perhaps most importantly, it allowed the unrestricted use of the operator’s hands, to operate any weapons during the frequently ‘hot’ extractions from a combat landing or pickup zone. Further, the rig was equally effective if an operator was wounded or unconscious.
