Wearing of uniform in public
I like to see the uniform on display outside the wire, reminds the public the Armed Forces exist. You all know they exist because you frequent this website, but, given the attention span of the public is more limited than my brain damaged goldfish, if the Armed Forces aren't in the face of the public they will be forgotten about. TBH around places like Colchester, Marham or Portsmouth you can pick out a serviceman in civvies at a hundred yards as poor Fusilier Rigby found out. Put it on, wear it with pride, and if you're aircrew don't slouch round with your hands in your pockets.
