This uniform thing is the same at Chillwell for reservists - you're ok walking around a service station in uniform on the way there from Brize, but when you are picked up by unit transport, to be taken straight home, you have to be in civvies, (though must admit I just took off the shirt to get out of the gate) The danger is, out of sight, out of mind and no-one will even think of it as a career. There was someone about a year ago produced GB stickers with a yellow ribbon around containing the caption Support Our Troops - unfortunately didn't catch on.
That was a great ad - made my spine tingle watching it.
