Forms of Address

Starfleet Commissioned Officers




Fleet Admiral is the highest attainable rank in Starfleet. Fleet Admirals, Admirals, Vice Admirals, and Rear Admirals are addressed as "Admiral", not Rear, Vice, etc.
Commodores are addressed as "Commodore".
The Commanding Officer of a vessel is called "Captain" in direct address, regardless of grade. Some smaller ships have captains which are not Captains; however, while on their vessels they are addressed as "Captain".
Commander
A Lieutenant Commander is addressed as "Commander" as well. At his pleasure, a Commander and above may address a Lieutenant Commander as "Mister", but he should know that he is giving offense to the officer by implying that he is a junior officer.
Lieutenant
Officers with the rank Lieutenant Junior Grade are addressed as "Lieutenant" when addressed by their rank.
Junior officers are addressed either by their ranks or as "Mister Smith". They should refer to each other in this manner. At the pleasure of senior officers, female junior officers may be called "Ms. Smith".
   
Marine Commissioned Officers




All Generals, regardless of their rank, are addressed as "General", not "Major General", "Brigadier General", etc.
By Starfleet tradition, the Marine Commanding Officer defers to the Starfleet Commanding Officer when aboard ship, and is generally outranked by him (although this is sometimes reversed for large contingents in some operations).
In direct address, Lieutenant Colonels are called "Colonel".
Major
Note that a Marine Captain is roughly equivalent to a Starfleet Lieutenant. The "honorary" rank of "Major" to said marines while on Starfleet vessels is ignored as the marines are generally referred to as "Marine Captain" to avoid confusion with the naval Captain of the ship.
First Lieutenant
In direct address, Second Lieutenants are called "Lieutenant".
   
Warrant Officers



Warrant Officers hold their position by "warrant", and are considered to outrank all Enlisted grades. WOs are generally found heading sub-departments such as Transporter Mechanisms or Shuttle Maintenance.
   
Enlisted Crewmen


All enlisted personnel of grades Chief Petty Officer to Master Chief Petty Officer are addressed as "Chief".


All Starfleet Enlisted Crewmen of grades Petty Officer Third Class to Petty Officer First Class are called "Petty Officer".


All "Crewmen" are called such, regardless of their grades. Enlisted crewmen are addressed solely by their rank or by the word "Crewman". Enlisted Crewmen can be called by last names, without "Mister" attached.






Marines are addressed by their rank. They are not called "Mister".

All "Privates" are called such, regardless of their grades.
