If your little pink body is endangered for the war effort (for the qualifying period) then you should get the campaign medal. SUch risks including but not limited to:
Enemy contact - yes.
Getting mortared inside the wire - yes.
Your aircraft being shot down - yes.
Your aircraft crashing on ops because it should be in the RAF Museum - yes.
etc.
Slipping on a puddle as you walk up to the pool bar for another mojito after a day playing with your joystick in a darkened room 12000 miles from theatre - er, maybe not.
Seriously, would you feel much self respect wearing that medal next to a Chinook mate who gets hosed with lead, RPGs and worse every time he goes flying? Really?
