A non-commissioned officer (also known as NCO or non-com) is an enlisted member of Starfleet or another military or service organization who has not attended officer training, but functions as a lower-ranking crewman with authority over other enlisted crewmen.
In Starfleet, anyone who is a petty officer (including specialists, yeomen and technicians) is a non-com, as they are senior to the lower crewman rank. This includes the more senior non-coms, such as chiefs.
Includes ranks of E3 (Petty Officer Third Class) to E9 (Master Chief Petty Officer).
