Starfleet Ranks and Uniforms

Starfleet Uniforms
Starfleet ranks are the identifying titles for the officers and enlisted members of Starfleet, under the United Federation of Planets. Aside from rank, all officers also held a position in a department. Within Starfleet, there exists three divisions of personnel, which handled all possible allotted tasks.


 * Red denotes Command and CONN. These are commanders, like COs and XOs, or administrative personnel, yeomen. They are also CONN and Flight Control officers.
 * Gold indicates Engineering, Operations, Tactical and Security. These were those who built, configured, allotted and repaired ship's systems. Security handles security on board, ranging from crowd control, the Brig and a number of related issues. Tactical Officers also wore this colour, with the Chief Tactical Officer posted on the Bridge.
 * Teal indicates Science, Medical and Counselling. These are the nurses, doctors, pharmacists, and orderlies of the Sickbay. They also analyse scientific data, and preform experiments.

Enlisted
Crewman (CRMN) Crewman is an enlisted rank of often limited responsibility or entry level duties. They are just getting started and are beginning to learn their trade. To progress further they must complete their divisional exam.

Petty Officer (PO) Petty officer is a subordinate non-commissioned officer rank, serving as a technician aboard a Starfleet vessel. They have learned their trade and are now applying it in the fleet.

Chief Petty Officer (CPO) Chief petty officer is a staff non-commissioned officer rank. Chiefs serve Starfleet as mentors to the lower enlisted, mainly due their experience on the ship. They have the ability to apply to become officers or warrant officers.

Senior Chief Petty Officer (SCPO) Senior chief petty officer is a staff non-commissioned officer rank. Acting as more are seasoned and exceptional SNCO compared to ordinary Chiefs. They typically work with Warrant Officers to help make their divisions a better place. They have a heavier voice and are largely responsible for training new Starfleet personnel.

Master Chief Petty Officer (MCPO) The MCPO serves directly under the CMCPO and assists them in overseeing the Enlisted Officers. They are responsible for the training of Enlisted ranks below theirs. They act as a buffer for all requests to the CMCPO only bringing news worthy of his attention.

Command Master Chief Petty Officer (CMCPO) The CMCPO is directly in charge of the enlisted side of Starfleet. They are responsible for all training and operations that the enlisted conduct. The rank acts as an advisor to the admiralty.

Warrant
Warrant Officer (WO) WOs are technically and tactically focused officers who perform the primary duties of technical leader, trainer, operator, manager, maintainer, sustainer, and advisor.

Chief Warrant Officer 2 (CWO2) CWO2s are advanced-level experts who perform the primary duties of a technical and tactical leader. They provide direction, guidance, resources, assistance, and supervision necessary for subordinates to perform their duties.

Chief Warrant Officer 3 (CWO3) CWO3s are senior-level experts in their chosen field. They typically have special mentorship responsibilities for other WOs and provide essential advice to commanders on WO issues.

Chief Warrant Officer 4 (CWO4) CWO4s are master-level experts that support major operations and division duties. They provide leader development, mentorship, advice, and counsel to Warrant Officers and branch officers.

Officers
Ensign (ENS) The most junior Starfleet Line rank. It is the rank bestowed on newly commissioned officers when they graduate from the commissioning program. Ensigns typically begin their careers as the most junior officers in the department of their chosen specialty. Ensigns who have strongly distinguished themselves in their academy class or on duty may sometimes be given posts as main-shift bridge officers.

Lieutenant Junior Grade (LTJG) The Starfleet line rank is immediately inferior to Lieutenant. Officers at this rank typically hold support positions on Starships and Starbases. At this rank, they have begun to prove their ability to perform acceptably in Starfleet, and typically begin to take on more senior roles in command situations. On rare occasions, those who post highly distinguished records during the commissioning program are granted the rank of Lieutenant Junior Grade upon graduation, bypassing the traditional junior rank of Ensign.

Lieutenant (LT) The Starfleet line rank immediately inferior to Lieutenant Commander. Officers at this rank typically have some command experience, and are occasionally appointed department heads on Starships.

Lieutenant Commander (LCDR) The Starfleet line rank immediately inferior to Commander. Officers with this rank typically hold positions as Starship department heads, or, in some cases, as commanding officer or first officer of a Starship.

Commander (CDR) The Starfleet line rank immediately inferior to Captain. Officers at this rank typically hold positions such as space station commander or first officer of important Starships.

Captain (CAPT) The most senior regular line rank in Starfleet. It is most often applied to Starship and Starbase commanders, and the adjutants and executives serving beneath admirals. This rank is usually considered a big transition, because it is often the first rank in which officers run a base of operation more or less by themselves.
