The late Nish Bruce - SAS - who mysteriously fell 5000ft from a light aircraft without a parachute told me the story of the US/Argie troops that were captured. He also told me a the plan to invade Buenos Aires. The SAS were to HALO into various streets, chainsaw down telegraph and lamp posts so that C-130's could land........
The way I heard it, the SAS were going to fly in on James Bond rocket packs...
