Coffman,
the HSP is more my era. Looks like a CVR (T) (Combat Vehicle Tracked-recce) on it. The version we dropped was the Scorpion, which looked like a small tank (someone will have a pic I am sure). Great fun to drive around , very speedy with the Jaguar engine. I was never quite sure of the likely scenario for using them. You could only carry one HSP per a/c whereas you could get two MSP's in. So a lot of space would be wasted out of not a huge number of a/c in the stream. Heaviest HSP I dropped was a grader at 35000 lbs. I think the Scorpion was more like 25000 lbs
