JTO,
An element of what you mention was an intended result of the run up to NEM and AFPS 15. The guys are inculcated through training with disparate sign on periods that the military is not necessarily a job for life, and many see an initial option point as just that, especially those with marketable skills outwith BRITMIL. An unintended consequence is probably that conditions of service, NEM becoming a reality and the plethora of other 'changes' have encouraged individuals across a swath of trades/occupations to leave before the system was expecting them to.
