I for one would wear trousers from Primark and shirts from Tesco to allow the ever-decreasing budget to focus it's effort on the things that really matter; aircraft, armour, bullets and quality of life (home and abroad).
However, despite my best efforts to turn my half-empty glass into a half-full one, I am quite sure that no matter how much moaning, be it on an official basis through forms and the like, or here on this forum, that nothing will change until the money starts rolling in from the Treasury.
Until the day comes that the quality of blues determines whether I carry out my tasks effectively or not, I agree with Shack37; wear it with pride. Thousands want to, few succeed.
