Does MoD still have that department near Swindon that provides definitions/translations of words and phrases used by MoD that don't appear in any dictionary? I'd never heard of them until just before retiring, when I overheard one of my young graduates talking to them on the phone. He'd a degree in English Lit and done the Shrivenham Defence Admin degree course (bloody waste of time that one), but couldn't make head nor tail of a URD he'd received from London.
