A private is a soldier, usually with the lowest rank in many armies. Soldiers with the rank of private may be conscripts or they may be professional (career) soldiers.
A non-commissioned officer (NCO) is a military officer who does not hold a commission. Non-commissioned officers usually earn their position of authority by promotion through the enlisted ranks. In contrast, commissioned officers usually enter directly from a military academy, officer training corps (OTC) or reserve officer training corps (ROTC), or officer candidate school (OCS) or officer training school (OTS), after receiving a post-secondary degree.
Military recruit training, commonly known as basic training or boot camp, refers to the initial instruction of new military personnel. It is a physically and psychologically intensive process, which resocializes its subjects for the unique demands of military employment.
Corporal is a military rank in use by the armed forces of many countries. It is also a police rank in some police services. The rank is usually the lowest ranking non-commissioned officer. In some militaries, the rank of corporal nominally corresponds to commanding a section or squad of soldiers.
Seaman recruit is usually the lowest rank used in navies around the world.
Airman basic (AB) is the lowest enlisted rank in the United States Air Force immediately below airman. The male form of rank designation also applies to women. The pay grade for airman basic is E-1.
Seaman apprentice is the second lowest enlisted rate in the U.S. Navy, U.S. Coast Guard, and the U.S. Naval Sea Cadet Corps just above seaman recruit and below seaman; this rank was formerly known as seaman second class.
The chart below represents the current enlisted rank insignia of the United States Air Force.
Seaman is a military rank used in many navies around the world. It is considered a junior enlisted rank and, depending on the navy, it may be a single rank on its own or a name shared by several similarly junior ranks.
Senior airman (SrA) is the fourth enlisted rank in the United States Air Force, just above airman first class and below staff sergeant. The rank designation is the same for male and female. It has a pay grade of E-4. Between its approval on 30 December 1975 and 19 March 1991, senior airmen wore sleeve chevrons with blue center stars instead of silver to distinguish them from the non-commissioned officer rank of "sergeant", also a pay grade of E-4. The latter was abolished in 1991 and the blue center star was changed to white to conform to all enlisted rank chevrons.
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.
Specialist is a military rank in some countries' armed forces. Two branches of the United States Armed Forces use the rank. It is one of the four junior enlisted ranks in the United States Army, above private (PVT), private (PV2), and private first class and is equivalent in pay grade to corporal; in the United States Space Force, four grades of specialist comprise the four junior enlisted ranks below the rank of sergeant.
A military reserve force is a military organization whose members (reservists) have military and civilian occupations. They are not normally kept under arms, and their main role is to be available when their military requires additional manpower. Reserve forces are generally considered part of a permanent standing body of armed forces, and allow a nation to reduce its peacetime military expenditures and maintain a force prepared for war. During peacetime, reservists typically serve part-time alongside a civilian job, although most reserve forces have a significant permanent full-time component as well. Reservists may be deployed for weeks or months-long missions during peacetime to support specific operations. During wartime, reservists may be kept in service for months or years at a time, although typically not for as long as active duty soldiers.
In the United States Armed Forces, the ranks of warrant officer and chief 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.
Airman first class (A1C) is the third enlisted rank in the United States Air Force, just above airman and below senior airman. The male form of rank designation also applies to women. The rank of airman first class is considered a junior enlisted rank, with the non-commissioned officers and senior non-commissioned officers above it.
An officer is a person who holds a position of authority as a member of an armed force or uniformed service.
Naval Air Technical Training Center (NATTC) is the parent command of the Airman Apprenticeship Training School, and provides technical training schools for nearly all enlisted aircraft maintenance and enlisted aircrew specialties in the U.S. Navy, U.S. Marine Corps and U.S. Coast Guard.
