An officer is a person who holds a position of authority as a member of an armed force or uniformed service.
Broadly speaking, "officer" means a commissioned officer, a non-commissioned officer (NCO), or a warrant officer. However, absent contextual qualification, the term typically refers only to a force's commissioned officers, the more senior members who derive their authority from a commission from the head of state.
The proportion of officers varies greatly. Commissioned officers typically make up between an eighth and a fifth of modern armed forces personnel. In 2013, officers were the senior 17% of the British armed forces,[1] and the senior 13.7% of the French armed forces.[2] In 2012, officers made up about 18% of the German armed forces,[citation needed] and about 17.2% of the United States armed forces.[3]
Historically armed forces have generally had much lower proportions of officers. During the First World War, fewer than 5% of British soldiers were officers (partly because World War One junior officers suffered high casualty rates). In the early 20th century, the Spanish army had the highest proportion of officers of any European army, at 12.5%, which was at that time considered unreasonably high by many Spanish and foreign observers.
Within a nation's armed forces, armies (which are usually larger) tend to have a lower proportion of officers, but a higher total number of officers, while navies and air forces have higher proportions of officers, especially since military aircraft are flown by officers and naval ships and submarines are commanded by officers. For example, 13.9% of British Army personnel and 22.2% of the RAF personnel were officers in 2013, but the British Army had a larger total number of officers.[1]
Commissioned officers generally receive training as generalists in leadership and in management, in addition to training relating to their specific military occupational specialty or function in the military.
Many militaries typically require university degrees as a prerequisite for commissioning, even when accessing candidates from the enlisted ranks.
Others, including the Australian Defence Force, the British Armed Forces, the Nepali Army, the Pakistan Armed Forces (PAF), the Swiss Armed Forces, the Singapore Armed Forces, the Israel Defense Forces (IDF), the Swedish Armed Forces, and the New Zealand Defence Force, are different in not requiring a university degree for commissioning, although a significant number of officers in these countries are graduates.[4][5]
In the Israel Defense Forces, a university degree is a requirement for an officer to advance to the rank of lieutenant colonel and beyond. The IDF often sponsors the studies for its officers in the rank major, while aircrew and naval officers obtain academic degrees as a part of their training programmes.
In the United Kingdom, there are three routes of entry for British Armed Forces officers.
The first, and primary route are those who receive their commission directly into the officer grades following completion at their relevant military academy. This is known as a Direct Entry (DE) officer scheme.
In the second method, individuals may gain a commission after first enlisting and serving in the junior ranks, and typically reaching one of the senior non-commissioned officer ranks (which start at sergeant (Sgt), and above), as what are known as Service Entry (SE) officers (and are typically and informally known as "ex-rankers"). Service personnel who complete this process at or above the age of 30 are known as Late Entry (LE) officers. [6][7]
The third route is similar to the second, in that candidates convert from an enlisted rank to a commission; but these are only taken from the highest ranks of SNCOs (warrant officers and equivalents). This route typically involves reduced training requirements in recognition of existing experience. Some examples of this scheme are the RAF's Commissioned Warrant Officer (CWO) course or the Royal Navy's Warrant Officers Commissioning Programme.[8][9]
In the British Army, commissioning for DE officers occurs after a 44-week course at the Royal Military Academy Sandhurst. The course comprises three 14 weeks terms, focussing on militarisation, leadership and exercises respectively.[10][11] Army Reserve officers will attend the Army Reserve Commissioning Course, which consists of four two-week modules (A-D). The first two modules may be undertaken over a year for each module at an Officers' Training Corps; the last two must be undertaken at Sandhurst.
Royal Navy officer candidates must complete a 30-week Initial Navy Training (Officer) (INT(O))course at Britannia Royal Naval College. This comprises 15 weeks militarisation training, followed by 15 weeks professional training, before the candidate commences marinisation.[12]
Royal Air Force (RAF) DE officer candidates must complete a 24-week Modular Initial Officer Training Course (MIOTC) at RAF College Cranwell. This course is split into four 6-week modules covering: militarisation, leadership, management and assessment respectively. [13]
Royal Marines officers receive their training in the Command Wing of the Commando Training Centre Royal Marines during a 15-month course. The courses consist not only of tactical and combat training, but also of leadership, management, etiquette, and international-affairs training.
Until the Cardwell Reforms of 1871, commissions in the British Army were purchased by officers. The Royal Navy, however, operated on a more meritocratic, or at least socially mobile, basis.
Commissioned officers exist in all eight uniformed services of the United States. All six armed forces of the United States have both commissioned officer and non-commissioned officer (NCO) ranks, and all of them (except the United States Air Force and United States Space Force) have warrant-officer ranks. The two noncombatant uniformed services, the United States Public Health Service Comm
