Tony,
I didn't join out of a sense of duty......more a desire to do a challenging and interesting job. Mere duty would not have cut the mustard I'm afraid, other options were available.
Some of the guys leaving now have been involved in some pretty tasty fighting for the past 13 years or so.....since GW2 we have been a little busy.
People wish to leave, but ironically, FRI is usually targeted at IPP. The people clamouring are at 6,8,10,13 years service.
The FRI would be good spent persuading a trained pilot not to take the chance and jump elsewhere for work. Believe me, it's a real draw.
But when Afghanistan finishes later this year, we can all take a "capability gap" and not have full manning for the next few years.....;-)
