An officer candidate school ( OCS ) is a military school which trains civilians and enlisted personnel in order for them to gain a commission as officers in the armed forces of a country. How OCS is run differs between countries and services. Typically, officer candidates have already attained post-secondary education, and sometimes a bachelor's degree , and undergo a short duration of training (not more than a year) which focuses primarily on military skills and leadership. This is in contrast with a military academy which includes academic instruction leading to a bachelor's degree.
84-756: The Non-Combatant Corps (NCC) was a corps of the British Army composed of conscientious objectors as privates, with NCOs and officers seconded from other corps or regiments. Its members fulfilled various non-combatant roles in the army during the First World War , the Second World War and the period of conscription after the Second World War. The Non-Combatant Corps (NCC) was first established by royal warrant in March 1916 as
168-582: A corps d'armée in 1815 for commanding his mixed allied force of four divisions against Napoleon I. When the British Army was expanded from an expeditionary force in the First World War, corps were created to manage the large numbers of divisions. The British corps in World War I included 23 infantry corps and a few mounted corps. The word was adopted for other special formations such as
252-515: A lieutenant general . During World War I and World War II , due to the large scale of combat, multiple corps were combined into armies which then formed into army groups . In Western armies with numbered corps, the number is often indicated in Roman numerals (e.g., VII Corps ). The Australian and New Zealand Army Corps was raised in 1914, consisting of Australian and New Zealand troops, who went on to fight at Gallipoli in 1915. In early 1916,
336-684: A 10-year program of training for Filipino Servicemen and Civilian Volunteers (Reserve), and forming the Philippine Army as the main ground forces of the Armed Forces of the Philippines . A transfiguration took place with some military personnel from the Philippine Constabulary being transferred to form the nucleus of the Philippine Army. However, the 10-year program was incomplete by the time World War II broke out in
420-457: A MEF headquarters group, a Marine division, a Marine aircraft wing, and a force service support group (re-designated as Marine logistics group in 2005). The pre– World War II Red Army of the former USSR had rifle corps much like in the Western sense with approximately three divisions to a corps. However, after the war started, the recently purged Soviet senior command ( Stavka ) structure
504-572: A battalion were ever trained or exercised. Early in the Second World War, Canada's contribution to the British-French forces fighting the Germans was limited to a single division. After the fall of France in June 1940, a second division moved to England, coming under command of a Canadian corps headquarters. This corps was renamed I Canadian Corps as a second corps headquarters was established in
588-518: A communications regiment (or a separate battalion). In 1945, air defence corps could include 1 anti-aircraft artillery brigade or division. Air defence fighters operating within the limits of responsibility of the KPVO was transferred to the corps. By the end of the war, there were 14 KPVO in the Active Army, of which 5 corps continued to carry out the tasks assigned to them even after the war, and
672-407: A corps is also a grouping of personnel by common function, also known as an arm , service , mustering or branch . In the British Army, an administrative corps performs much the same role – for personnel that otherwise lack them – as a ceremonial regiment . An administrative corps therefore has its own cap badge , stable belt , and other insignia and traditions. In some cases, the term corps
756-594: A corps varies greatly, but two to five divisions and anywhere from 40,000 to 80,000 are the numbers stated by the US Department of Defense. Within military terminology a corps may be: These usages often overlap. Corps may also be a generic term for a non-military organization , such as the US Peace Corps and European Solidarity Corps . In many armies, a corps is a battlefield formation composed of two or more divisions , and typically commanded by
840-577: A corps-sized formation in the First World War; the Canadian Corps was unique in that its composition did not change from inception to the war's end, in contrast to British corps in France and Flanders. The Canadian Corps consisted of four Canadian divisions. After the Armistice, the peacetime Canadian militia was nominally organized into corps and divisions but no full-time formations larger than
924-500: A dedicated Cavalry Corps of three divisions and horse artillery assigned to the corps headquarters. In the early years of the war, field artillery was either part of an artillery reserve under direct army control or assigned to individual divisions. However, after the Battle of Chancellorsville the divisional artillery was placed under corps control, with each corps assigned a brigade of between four and six batteries commanded by

This staff consisted of a chief of cavalry, a chief of artillery, and representatives of the War Department 's various bureaus: an assistant adjutant general , a quartermaster , an assistant inspector general , a commissary of subsistence, an ordnance officer (all with the rank of lieutenant colonel ), and a medical director. However, there were no dedicated combat service support formations as part of
1092-480: A number of independent brigades or regiments and supporting units. The Chinese Republic had 133 corps during the Second Sino-Japanese War . After losses in the early part of the war, under the 1938 reforms, the remaining scarce artillery and the other support formations were withdrawn from the division and was held at corps, or army level or higher. The corps became the basic tactical unit of
1176-413: A numerically superior foe. This allowed Napoleon I to mass the bulk of his forces to effect a penetration into a weak section of enemy lines without risking his own communications or flank. This innovation stimulated other European powers to adopt similar military structures. The corps has remained an echelon of French Army organization to the modern day. As fixed military formation already in peace-time it
1260-868: A result of the Military Service Act 1916 , which introduced conscription in Britain for the first time. The British Army, which had no precedents or guidelines for conscription, formed the corps to provide a military unit for a category of conscientious objectors who had been conscripted but were prepared to accept only non-combatant duties, which was guaranteed in the case of the NCC. It was commanded by regular army officers and NCOs, and its members wore army uniform and were subject to army discipline, but did not carry weapons or participate in battle. Their duties were mainly to provide physical labour (building, cleaning, loading and unloading anything except munitions) for
1344-399: A soldier as part of a specific corps (or sometimes individual battalion). This lanyard is a woven piece of cord which is worn on ceremonial uniforms and dates back to the issue of clasp knives in the early 20th century which were secured to the uniform by a length of cord. If a soldier is posted to a unit outside of their parent corps, except in some circumstances the soldier continues to wear
1428-1066: A written exam, physical tests, and several interviews for consideration. Admitted applicants are ordered enlistment in the Army Cadet Military School in Goesan . At graduation, candidates earn a commission with the rank of Second Lieutenant . The Republic of Korea Navy and the Republic of Korea Marine Corps have maintained the most rigorous candidate school program in South Korea. Both ROKN and ROKMC officer candidates earn commissions together at Republic of Korea Naval Academy in Changwon , while their training programs are distinct. ROKMC candidates will be sent to Marine Corps School in Pohang , while ROKN candidates remain in Changwon . Petty officers in active duty who have earned
1512-490: A year after conscription was reintroduced. The corps was composed of conscripted men who had been registered as non-combatants by tribunals. Unlike in the First World War, there were also enlisted members of the NCC who had been deemed not physically competent for combatant service. This gave the Corps less of a stigma than it had had twenty five years earlier. It was divided into 14 companies, commanded mostly by veteran officers of
1596-682: Is 30 weeks, whilst the Royal Marines course lasts 15 months and is split between CTCRM and BRNC. Royal Air Force officer cadets undergo a 24 week course at RAFC. Once graduated and commissioned, officers of all services may undertake further specialist post-graduate training appropriate to their military profession, such as flying training, engineering, logistics; and these will invariably multi-service training establishments. One example being Amport House , where military chaplains for all service branches receive their military theology training until it closed in 2020; it has since been relocated to
1680-505: Is also used informally, for looser groupings of independent regiments and other units – and without many or any unifying regalia , military traditions or other accoutrements – such as the Royal Armoured Corps or the "Corps of Infantry". In Australia, soldiers belong foremost to a corps which defines a common function or employment across the army. The Australian Army has a system of coloured lanyards, which each identify
1764-480: Is an operational-tactical formation (in the past - the highest tactical formation) of the former Soviet Air Defence Forces and now Russian Air Defence Forces /Aerospace Forces. The purpose of the such a corps is to protect important administrative, industrial and economic centers and regions of the country, groupings of troops (forces) and military facilities within the established limits of responsibility against air strikes. In organizational terms, an air defence corps

Unlike other countries, OCS is the only route to a commission in the SAF. Even selected cadets who hold scholarships to train in friendly service academies must complete two thirds of OCS and receive their commission before undergoing further training overseas. OCS in Singapore lasts approximately 38 weeks. The first term consists of military knowledge applicable to all services, including military history and military law . Subsequently, Officer Cadets are streamed into their services based on aptitude and personal preference, and receive training specific to their service. In South Korea, Officer Candidate School (학사사관) were modeled on OCS programs of
