The Reserve Officers' Training Corps is a group of college- and university-based officer-training programs for training commissioned officers of the United States Armed Forces.
A midshipman is an officer of the lowest rank in the Royal Navy, United States Navy, and many Commonwealth navies. Commonwealth countries which use the rank include Canada, Australia, Bangladesh, Namibia, New Zealand, South Africa, India, Pakistan, Singapore, Sri Lanka, and Kenya.
A cadet is a student or trainee within various organisations, primarily in military contexts where individuals undergo training to become commissioned officers. However, several civilian organisations, including civil aviation groups, maritime organisations, and police services, also designate their trainees as cadets.
Officer cadet is a rank held by military cadets during their training to become commissioned officers. In the United Kingdom, the rank is also used by members of University Royal Naval Units, University Officer Training Corps and University Air Squadron; however, these are not trainee officers with many not choosing a career in the armed forces.
Officer candidate or officer aspirant (OA) is a rank in some militaries of the world that is an appointed position while a person is in training to become an officer. More often than not, an officer candidate was a civilian who applied to join the military directly as an officer. Officer candidates are, therefore, not considered of the same status as enlisted personnel.
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.
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.
The Naval Reserve Officer Training Corps (NROTC) program is a college-based, commissioned officer training program of the United States Navy and the United States Marine Corps.
The United States Marine Corps Officer Candidates School (OCS) is a training regiment designed to screen and evaluate potential Marine Corps Officers. Those who successfully complete the period of instruction are commissioned as Second Lieutenants in the United States Marines. Unlike the other United States military services, the majority of Marine Corps officers complete OCS to earn a commission; the exceptions are midshipmen from the United States Naval Academy, limited duty officers and warrant officers, and inter-service transfers. It is located at Marine Corps Base Quantico.
The Naval Education and Training Command (NETC) is an enterprise-level shore command of the United States Navy with more than 19,000 military and staff personnel at more than 1,640 subordinate activities, sites, districts, stations, and detachments throughout the world, and was established in 1971. NETC recruits, trains and delivers those who serve the nation, taking them from "street to fleet" by transforming civilians into highly skilled, operational, and combat ready warfighters. In 2018, accessions management and distribution functions of the Bureau of Naval Personnel (BUPERS) were realigned under NETC and Navy Recruiting Command (NAVCRUITCOM) now serves as a subordinate command to NETC.
A naval aviator is a commissioned officer or warrant officer qualified as a crewed aircraft pilot in the United States Navy or United States Marine Corps. United States Coast Guard crewed aircraft pilots are officially designated as "Coast Guard aviators", although they complete the same undergraduate flight training as Navy and Marine Corps crewed aircraft pilots, and are awarded the same aviation breast insignia.
Pay grades are used by the eight structurally organized uniformed services of the United States, as well as the Maritime Service, to determine wages and benefits based on the corresponding military rank of a member of the services. While different ranks may be used among the eight uniformed services, pay grades are uniform and equivalent between the services and can be used to quickly determine seniority among a group of members from different services. They are also essential when determining a member's entitlements such as basic pay and allowances.
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.
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 Recruit Training Command, Great Lakes, is a command unit within the United States Navy primarily responsible for conducting the initial orientation of incoming recruits, also known as boot camp and recruit training, or RTC. It is part of Naval Service Training Command. It is a tenant command of Naval Station Great Lakes in the city of North Chicago, Illinois, in Lake County, north of Chicago.
The US Navy had four programs for the training of naval aviators.
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 Junior Reserve Officers' Training Corps (JROTC) is a federal program sponsored by the United States Armed Forces in high schools and also in some middle schools across the United States and at US military bases across the world. The program was originally created as part of the National Defense Act of 1916 and later expanded under the 1964 ROTC Vitalization Act.
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 students enrolled in the Naval Science Institute or Officer Candidate School, personnel will come to Officer Training School having already received their commission or warrant.
