Dave, ah well, I'm sorry mate, I've never heard of them but I guess it is just another of these wonderful ideas our PC loving politicians and the rather poor commanders we have had recently thats made our armed forces into the equally fluffy fun loving organisation it is nowadays. Lets face it they can change whatever they like at a stroke of a pen, who gives a toss for tradition anyway!
I notice the Army Sergeant Major (WO1) is a Guardsman, strange that - the only army regiment not decimated by 30 years of disbandments or whatever the government called the disbandments the last time.
I'm off to let the Royal Air Force discuss their own Warrant Officers as I should have in the beginning!
