Sergeant

Sergeant is a military or police rank, generally associated with people who aren't commissioned officers. Commonly, sergeants are used as the immediate supervisors of the essentially unranked soldier or policeman. This fact is made particularly clear in UNIT stories, as when John Benton is shown leading ordinary privates in DW: The Mind of Evil, or when the issue of rank plays an important subtextual role, like in MA: The Eye of the Giant.

"Sergeant" can also be an ordinary name, though such instances are uncommon and even rare in Doctor Who history.

The following list is divided into broad types of sergeant, and then alphebetised within each of those types.

Police
Though most police sergeants seen in the DWU have in fact been British, or at least from Earth, this section can include people who were in any civilian police force, on any planet.
