Well, not that anyone will believe me, but they DID find American combatants in the Falklands - they were Snipers. At the time it was always a query as to why the Argentinians had such good Snipers - given that they did not have any such beast in the Army/Marines and there was no organised Sniper Training for thier forces. They were particularily better equipped than we were - remember we were still using the old 7.62mm L42's in 1982 and they were getting worn out(read ****e!). And IR Night Sights were in thier infancy.
In fact on our side they were almost non-existant - mainly due to the fact they went "missing" during delivery - they were actually delivered to the SWO at RAF Marham at one point! - basically they wanted them "down South" quickly and 55 & 57 Sqns were the quickest delivery method to Wideawake.
The SWO didn't discover he had them for quite some time before he expidited them - not his fault - he didn't order them! SNAFU supply line/panic buy.
The gentlemen when found on the Islands had better kit than we had - very high-end IR Gear. I can assure you that when the Paras had finished night-ops with several of thier blokes Sniped they were in no mood to piss-about. They were escorted-off and 'shot whilst attempting to escape".
Special Branch investigation ! Ha! don't make me laugh - what were they going to do - dig up the mass-graves of Argentinian dead - crawl around all the minefields looking for bodies?
Another thing - find out about the American Air Force guy who solved all the problems on the A4's - particularily the ejection seat problems - but I guess HE didn't exist either!
