19a throat. In his/her clues the compiler of this crossword regularly uses men(plural) as clue for OR and I assume this is a reference to other ranks (non NCOs) in the army. However in my army days OR was always singular and was commonly pluralised as ORs. I think this still applies today.
Sorry if I'm being pedantic
