Like which? I haven't heard any, and you said they took the rank structure from the army (makes sense as it was the USAAF).

In GB it's only the army that has this rank structure. Your police forces have the same too. Here it's Constable, Sergeant, Inspector (cf LT), Chief Inspector (cf Capt), Superintendent (cf Major), Chief Superintendent (cf Colonel), Chief Constable or (in the London Met Police) Commissioner (cf General)
