Sgt. Fred Colon

Colon is a sergeant in the Ankh-Morpork City Watch, and appears to have been so for a long time. He was a corporal in the Watch at the time Samuel Vimes first joined, and subsequent to this spent some time in the army (the Duke of Quirm's Middleweight Infantry and then the Duke of Eorle's First Heavy Infantry), before returning to the Watch
He is described on several occasions as "one of nature's sergeants". He is overweight, and prefers to avoid trouble and exertion. He is also rather unimaginative. When not on desk duty (a post he gets more often than other sergeants, due to being responsible for working out the rota), he generally "guards" bridges or large buildings against theft. His reasoning is that until someone attempts to steal the geographic feature in question, he can lean against it and stay out of danger (as well as the wind).
