Top stuff.
This sounds like a fantastic use of the limited funds HM Treasury gives us, I sincerely hope some Navy chumpster at Fleet/MoD got a star for thinking of this one.
This reminds me of the really useful RAF bags that are too small to hold more than some PT kit and a squash racket..... (I cut the crest off mine and use it for laundry).....
Or the 'Royal Air Force' CS95 badges.....
Or the new No1 uniforms for ranks below WO.....
Or tit enhancement jobs for men.....
Or EO trg....Doctrine....U need 2 know.....etc, etc....
PS: Any serviceman who can't tell a member of the RN from the RAF by looking at the rank slides shouldn't be in the mob....
..... and member of Joe Public who can't do likewise, clearly has no interest in the military.... So who gives a cr@p what they say at airshows?
