An officer is a member of a group typically in the areas of the military, police, or some other form of authority. In a military service, an officer's typical role is to command and direct, maintain discipline and make plans and provisions for operation. Certain organizations have special criteria in order to achieve the status of officer.

Commission Edit

In a military service, a commission is an order from the service's supreme authority, such as its commander-in-chief, authorizing an individual to legally hold a military rank, with all the privileges and responsibilities of said rank. A commission usually appoints an individual to hold an officer's rank.

In times of conflict, a temporary commission could appoint an officer to command rank to replace an incapacitated or killed commanding officer. Commander William T. Riker, for example, was granted a field commission promoting him to Captain and given command of the USS Enterprise-D when the ship's commanding officer, Captain Jean-Luc Picard, was abducted and assimilated by the Borg during their first attempt to assimilate Earth. (TNG: "The Best of Both Worlds", "The Best of Both Worlds, Part II")

In situations where contact with Starfleet is not possible for very extended periods, a commanding officer has the authority to grant commissions to officers under his or her command, or revoke their existing commissions, i.e. he/she has the authority promote or demote his/her officers. Good examples of this are when Captain Kathryn Janeway, commanding officer of the USS Voyager, promoted her Chief Tactical Officer and Security Chief, Lieutenant Tuvok, to the higher rank of Lieutenant Commander, or when she demoted her Flight Controller, Lieutenant Junior Grade Thomas E. Paris, to Ensign. (VOY: "Revulsion", "Thirty Days"). After a year of exemplary service, she re-promoted him to his former rank. (VOY: "Unimatrix Zero")

Starfleet Edit

In the Federation Starfleet, an officer or commissioned officer is an individual who has attended, and graduated from the four-year cadet program of Starfleet Academy. Upon graduation from the Academy, the cadet is granted a commission appointing him or her to Starfleet's most junior officer's rank: that of Ensign. With the commision comes a Bachelor's degree in his or her major field of academic study, be it the Pure Sciences, Medicine, Military Science, etc.

Commissioned officers are distinguished from non-commissioned officers and other crewmembers through the use of a rank structure.
