Give it to the Para's.
Wrong answer...
25 years ago the RAF Regiment were far more experienced in the air than the Parachute Regiment. The Paras were jumping a couple or three times a year if they were lucky. II Sqn. was doing an average of 10 per year. II Sqn was also the unit used to trial new stuff like the "stretched" C-130 and the "Wedge" then both.
I'm sure not much has changed in that regard.
