If only it was that easy, kitbag. What about those that only fly over theatre, have zero operational risk as they aren't based in theatre and still get a medal?
Don't think they'll qualify then. The specific example given by the MOD bloke seems simple enough even for me to understand; accrue time on the ground in theatre (small chunks to = 45 days, or continuously for 30 days), get recognised for it
As for the guff about PJHQ and others out of the declared operational area deserving it ....
