Abbreviations for crew commander and crewman

[myself.only]

If anyone could pls tell me the correct abbreviations for crew commander and crewman.
Searching the forum and my manual of abbreviations, I couldn't find either.
Currently, I've got people using CC for crew commander and chief clerk, so any help would be appreciated.
Thanks.

They are the same abbreviation.

It's designation is decided on by the context it's used in.

"Go see the CC  (Chief Clerk) about your claim"

"The CC (crew commander) of 13C is giving orders at 13:00"

crmn = crewman
