Just an observation, but; not ALL of the 'experience' is leaving, SOME of it is. The military is constantly evolving (i.e. shrinking at the moment), PVR is part of the process of allowing people to leave rather than making them redundant. It's interesting that throughout the (short) history of the RAF there are those, e.g. stopstart's Dad, who have and will always describe it as being in a 'shocking state'. They tend to be the same kind of people that read the Daily Mail and rant about everything that exists outside of their own cosy little world.
Many actually choose to stay and adopt a more pragmatic/progressive outlook and approach what is still a rewarding career without the frequently negative viewpoint of the majority who inhabit this forum.
