When I have a 'Gozomee head' on, all I wish to do is get on a jet at BAS and get into a car (ideally driven by DCoS) at BZN and go home. There is enough support from friends, family, curry house and pub to complete a full reset. I appreciate though that not everybody has that luxury and the differences exist between service, task completed, and age of individual.
That said; it should be a single service procedure rather then an ARMY Rule OK mandate. The Army already bully certain members of the RAF by mandating that they can complete RAF PDT but must also complete Army PDT (OpTag) in addition, prior to deployment. Somebody in the RAF Chain of Command needs to put the senior members of the Army fraternity back in their box, especially in regard to joint units.
Youngsters on tour have their needs, which can be quite different from mature members of the armed forces. This is like the walking-out rules in NI being written for the benefit of three pissed paras in a Ford Fiesta.
