This word was mentioned on the "Search for an Aly Star" thread here. http://www.arrse.co.uk/weapons-equipment-rations/46615-search-%2Aally%2A-star-294.html#post3797500 Whts seems as if it has remained in the Guards as ally There was a general nicknamed "Bolo" Lashmer Gordon Whistler - about as high as you can get as a non psc offcier. Lashmer Whistler - Wikipedia, the free encyclopedia Did he get his name from his wary behavioiur or ally dress sense? As GOC 3Div he certainly stuck a warry pose "I saw an infantry battalion on its way into battle. They were resting on both sides of the road when Bolo came back from the sharp end. He was driving himself, flag flying and his hat, as usual, on the back of his head. Every man stood up and waved to him as he went past, laughing and waving in reply" (from the wikipedioa article) Can anyone elabourate on the origins of the word and how it was used in the past?
