Pretty sure your right TH...can't see the lightning bolts, but looking closer at the bottom of the spear tip, the curve isn't as pronounced as it is on the USASOC tip. So, maybe a short AND a long tab are hiding under that strap!
It does look like there might be a triple canopy there. The long tab looks too far apart from the airborn tab above the unit patch. Its just an old photo and hard to tell. Beret doesnt have the usual flash, so I originally thought foreign soldier attached, but in my time when we had the brits attached to our group for training for some time, they still wore their uniforms and we wore ours when we were cross training with different units. Things change so much over the years in sf, so anything is possible.
We used the mc-4 system. It worked both for haho and halo operations. I have never jumped with any civilian chutes. Dont think i can get cleared medically due to all the injuries to spine and head. I do miss it a lot.
