Hairy!

Did you know that in the Navy you have to make an official request to grow a beard? And then, you have to grow a "full set" and present yourself for inspection to the Master at Arms, who will decide whether or not you are allowed to keep it.  Apart from medical or religious reasons, beards are not permitted at all in the Army or RAF, although moustaches are.  There's one exception to this - there's a particular traditional post in the Army called Pioneer Sergeant, who was a sort of blacksmith cum logger cum path-clearer cum general hardware operative and who was allowed to wear a beard on parade, and carry an axe in place of a rifle. And by the way, the rule in the RAF is that moustaches must not be wider than the mouth, and therefore the famous "handlebar" moustache is not in fact allowed!
