Command master chief petty officer (CMDCM) is an enlisted rating in the United States Navy and U.S. Coast Guard, as well as the Japan Maritime Self-Defense Force.
In the United States Navy, officers have various ranks. Equivalency between services is by pay grade. United States Navy commissioned officer ranks have two distinct sets of rank insignia: On dress uniform a series of stripes similar to Commonwealth naval ranks are worn; on service khaki, working uniforms, and special uniform situations, the rank insignia are identical to the equivalent rank in the US Marine Corps.
A United States military occupation code, or a military occupational specialty code, is a nine-character code used in the United States Army and United States Marine Corps to identify a specific job. In the United States Air Force, a system of Air Force Specialty Codes (AFSC) is used. In the United States Navy, a system of naval ratings and designators are used along with the Navy Enlisted Classification (NEC) system. A system of ratings is also used in the United States Coast Guard.
Chief Warrant officer is a senior warrant officer rank, used in many countries.
The surface warfare insignia is a military badge of the United States Navy which is issued to U.S. Navy personnel who are trained and qualified to perform duties aboard United States surface warships. There are presently four classes of the surface warfare pin, being that of line, staff, special operations, and enlisted. The line and enlisted surface warfare badges may be earned by United States Coast Guard personnel assigned to Navy commands. The various badge types are as follows:
The Naval Aviation Supply Corps insignia is a military badge of the United States Navy which is awarded to Naval Aviation Supply Officers (NASOs) of the Navy Supply Corps who have qualified for duties as a Supply Officer in support of naval aviation and are also qualified to serve in duty assignments onboard aircraft carriers. The Aviation Supply Corps insignia is one of four warfare badges issued to Supply Corps officers by the U.S. Navy. The others are the Navy Expeditionary Supply Corps Officer Badge, Surface Warfare Supply Badge, and the Submarine Supply Corps Badge.
Insignias and badges of the United States Navy are military badges issued by the United States Department of the Navy to naval service members who achieve certain qualifications and accomplishments while serving on both active and reserve duty in the United States Navy. Most naval aviation insignia are also permitted for wear on uniforms of the United States Marine Corps.
In the United States Armed Forces, a line officer or officer of the line is a U.S. Navy or U.S. Marine Corps commissioned officer or warrant officer who exercises general command authority and is eligible for operational command positions, as opposed to officers who normally exercise command authority only within a Navy Staff Corps. The term line officer is also used by the U.S. Air Force and U.S. Coast Guard to indicate that an officer is eligible for command of operational, viz., tactical or combat units. The term is not generally used by officers of the U.S. Army – the roughly corresponding Army terms are basic branch and special branch qualified officers, although the concepts are not entirely synonymous, as some Army special branch officers are eligible to hold command outside their branch specialty.
The United States Navy Reserve (USNR), known as the United States Naval Reserve from 1915 to 2005, is the Reserve Component (RC) of the United States Navy. Members of the Navy Reserve, called Reservists, are categorized as being in either the Selected Reserve (SELRES), the Training and Administration of the Reserve (TAR), the Individual Ready Reserve (IRR), or the Retired Reserve.
An unrestricted line officer is a designator given to a commissioned officer of the line in the United States Navy, who is eligible for command at sea of the navy's warfighting combatant units such as warships, submarines, aviation squadrons and SEAL teams. They are also eligible to command the higher echelons of those units, such as destroyer and submarine squadrons, air wings and air groups, and special warfare groups.
A limited duty officer (LDO) is an officer in the United States Navy or United States Marine Corps who was selected for commissioning based on skill and expertise. They are the primary manpower source for technically specific billets not best suited for traditional Unrestricted Line, Restricted Line, or Staff Corps career path officers. Per Title 10, U.S. Code, an LDO is a permanent commissioned officer appointed under section 8139 in a permanent grade above chief warrant officer, W-5, and designated for limited duty.
In the United States Navy, commissioned officers are either line officers or staff corps officers. Staff corps officers are specialists in career fields that are professions unto themselves, such as physicians, lawyers, civil engineers, chaplains, and supply specialists. For example, a physician can advance to become the commanding officer (CO) of a hospital, the medical hospital on a hospital ship or large warship, or a medical school; or the Chief of the Medical Corps or of the Bureau of Medicine and Surgery. A supply officer can become the CO of a supply depot or a school, or the head of the Naval Supply Systems Command, etc.
The United States Navy's Officer Candidate School provides initial training for officers of the line and select operational staff corps communities in the United States Navy. Along with United States Naval Academy (USNA) and Naval Reserve Officer Training Corps (NROTC), OCS is one of three principal sources of newly commissioned naval officers.
In the United States Armed Forces, the ranks of warrant officer are rated as officers above all non-commissioned officers, candidates, cadets, and midshipmen, but subordinate to the lowest officer grade of O‑1. This application differs from the Commonwealth of Nations and other militaries, where warrant officers are the most senior of the other ranks, equivalent to the U.S. Armed Forces grades of E‑8 and E‑9.
A direct commission officer (DCO) is a United States uniformed officer who has received an appointed commission without the typical prerequisites for achieving a commission, such as attending a four-year service academy, a four-year or two-year college ROTC program, or one of the officer candidate school or officer training school programs, the latter OCS/OTS programs typically slightly over three months in length.
The United States Navy has nearly 500,000 personnel, approximately a quarter of whom are in ready reserve. Of those on active duty, more than eighty percent are enlisted sailors, and around fifteen percent are commissioned officers; the rest are midshipmen of the United States Naval Academy and midshipmen of the Naval Reserve Officer Training Corps at over 180 universities around the country and officer candidates at the navy's Officer Candidate School.
An officer is a person who holds a position of authority as a member of an armed force or uniformed service.
The Naval Officer Training Command Newport is a command unit of Naval Education and Training Command, located on Naval Station Newport in Newport, Rhode Island that is responsible to the Chief of Naval Education and Training for the development of civilians, enlisted, and newly commissioned personnel for service in the fleet as Naval Officers. Outside of the requisite physical readiness testing, the programs are academic in nature, and with the exception of the student enrolled in the Naval Science Institute or Officer Candidate School, personnel will come to Officer Training School having already received their commission or warrant.
