When the troops on the ground secure an LZ are they doing it for themselves or for the RAF Chinnys to land on?? In which case who's working for who? When a Herc/C-17/Tri*/VC10 does a sweeper/trail/tanking for a Harrier/Typhoon/GR4 is it an RAF sortie or does that also come under 'Army Suport' as ultimately that is their role in the grand scheme of things...
Oooer, think this could run and run...
