If this isnt a wind up it will be another nail in the coffin of squadron life. A few years ago at Lyn. a certain highly popular!! Sqn boss dictated the type of civvies you must wear off duty, if "popping into squadron" (to pick up next route details etc) . Result was not a squadron of well turned out Cranwell clones, but an empty tea bar and everyone avoiding the place.
However, it will only be enforced for a few months before its forgotten, I was at Cranwell when you were told that 'only' the RAF issue rucksack could be used to carry kit, but if you had less that 3 years to do, you didnt get one issued, so despite being twice challenged by the SWO, I insisted that I was in my last 6 months and walked away, despite being signed in until 2020!
