A military academy or service academy (in the United States) is an educational institution which prepares candidates for service in the officer corps. It normally provides education in a military environment, the exact definition depending on the country concerned.
Three types of academy exist: pre-school-level institutions awarding academic qualifications, university-level institutions awarding bachelor's degree level qualification, and those preparing officer cadets for commissioning into the armed services of the state.
A naval academy is either a type of military academy (in the broad sense of that term) or is distinguished from one (in the narrow sense). In U.S. usage, the United States Military Academy and the United States Naval Academy are both service academies.
The Royal Danish Naval Academy was set up in 1701, making it the oldest military academy in existence. The Royal Military Academy, Woolwich was set up in 1720 as the earliest military academy in Britain. Its original purpose was to train cadets entering the Royal Artillery and Royal Engineers. In France, the École Royale du Génie at Mézières was founded in 1748, followed by a non-technical academy in 1751, the École Royale Militaire offering a general military education to the nobility. French military academies were widely copied in Prussia, Austria, Russia and even minor powers, including Turin and the Kingdom of Savoy, in the late 18th century.
By the turn of the century, under the impetus of the Napoleonic Wars and the strain that the armies of Europe subsequently came under, military academies for the training of commissioned officers of the army were set up in most of the combatant nations. These military schools had two functions; to provide instruction for serving officers in the functions of the efficient staff-officer, and to school youngsters before they gained an officer's commission. The Kriegsakademie in Prussia was founded in 1801 and the École spéciale militaire de Saint-Cyr was created by order of Napoleon Bonaparte in 1802 as a replacement for the École Royale Militaire of the Ancien Régime (the institution that Napoleon himself had graduated from).
The Royal Military College, Sandhurst, in England was the brainchild of John Le Marchant in 1801, who established schools for the military instruction of officers at High Wycombe and Great Marlow, with a grant of £30,000 from Parliament. The two original departments were later combined and moved to Sandhurst. In the United States, the military academy at West Point was founded in 1802 and became popular in the 1860s.
A military school teaches children (primarily boys) of various ages (elementary school, middle school or high school) in a military environment which includes training in military aspects, such as drill. Many military schools are also boarding schools, and others are simply magnet schools in a larger school system. Many are privately run institutions, though some are public and are run either by a public school system (such as the Chicago Public Schools) or by a state.
A common misconception results because some states have chosen to house their juvenile criminal populations in higher-security boarding schools that are run in a manner similar to military boarding schools. These are also called reform schools, and are functionally a combination of school and prison. They attempt to emulate the environment of military boarding schools in the belief that a strict structured environment can reform these children. This may or may not be true. However, their environment and target population are different from those of military schools.
Popular culture sometimes shows parents sending or threatening to send unruly children off to military school (or boarding school) to teach them good behavior (e.g., in the "Army of One" episode of The Sopranos, Tony and Carmela Soprano consider sending their son, AJ, to the Hudson Military Institute). A similar situation appears in Bill & Ted's Excellent Adventure, while other fictional depictions don't show military academies as punishment (threats) (ex. Damien: Omen II and The Presidio.
A college-level military academy is an institute of higher learning of things military. It is part of a larger system of military education and training institutions. The primary educational goal at military academies is to provide a high quality education that includes significant coursework and training in the fields of military tactics and military strategy. The amount of non-military coursework varies by both the institution and the country, and the amount of practical military experience gained varies as well.
Military academies may or may not grant university degrees. In the U.S., graduates have a major field of study, earning a Bachelor's degree in that subject just as at other universities. However, in British academies, the graduate does not achieve a university degree, since the whole of the one-year course (nowadays undertaken mainly but not exclusively by university graduates) is dedicated to military training.
There are two types of military academies: national (government-run) and state/private-run.
Has several military academies:
Canada currently has one military-theme private boarding school open for students at the pre-university level, Robert Land Academy (RLA), which is located in West Lincoln, Ontario. Founded in 1978, it is an all-boys' institute whose funding arises solely from tuition fees. The Academy is an institute fully accredited by the province of Ontario, which accepts students from Grade 6 to Grade 12 (the Ontario Academic Credit level).
Canada formerly had three university level service academies, the Canadian Military Colleges. These included the Royal Military College of Canada (RMC) in Kingston, Ontario, Royal Roads Military College (RRMC) in Victoria, British Columbia and the Collège militaire royal de Saint-Jean (CMR) in Saint-Jean-sur-Richelieu, Québec. RMC was founded in 1876, RRMC in 1941 and CMR in 1954. By the 1960s all three institutions were providing military education to officer cadets of all three elements in the Canadian Forces; the navy, army and air force; and RMC received the authority to grant academic degrees in Arts, Science and Engineering.
Graduates of the Colleges are widely acknowledged to have had a disproportionate impact in the Canadian services and society, thanks to the solid foundations provided by their military education. Military discipline and training, as well as a focus on physical fitness and fluency in both of Canada's two official languages, English and French, provided cadets with ample challenges and a very fulfilling experience. In 1995 the Department of National Defence was forced to close Royal Roads Military College and Collège militaire royal de Saint-Jean due to budget considerations, but Royal Military College of Canada continues to operate. Royal Roads reopened as a civilian university in the fall of 1995, and is maintained by the Government of British Columbia. In 2007, the Department of National Defence reopened Collège militaire royal de Saint-Jean as a preparatory and first year college.
National Defense Academy (NDA) of Georgia is a descendant of the first Georgian "Junker School" which was established in 1919 right after the declaration of independence. Establishment of the military school was very important for the identity of a new democratic nation-state. The school was abolished after Soviet occupation of Georgia in 1921.
"Davit Aghmashenebeli National Defense Academy of Georgia" was founded on May 28, 1993. The length of studies at the Academy had been defined for 4 years. In 2005, due to the need of the growth of the personnel strength of the Georgian Armed Forces (GAF), the system of the Academy has been transformed to retain only the 18-month-long officer training courses. A bachelor's degree has been defined as a prerequisite for the admission of the cadets.
In 2010, the NDA has undergone a new wave of the reforms to include entire officer education system. As a result, in 2011, Cadet Bachelor School, Junior Officer Basic School, Aviation and Air Defense Officer Basic School, Medical Officer School, Captain Career School, Command and General Staff School, School of Advance Defense Studies and Language Training School were included within the NDA.
Upon entry into NDA, cadets sign a contract with the MoD for 10 years of military service, of which 4 years are dedicated to studies and 6 years – to consequent military service. Cadets receive the rank of Lieutenant upon graduation.
NDA is established by the MoD with the status of the Legal Entity of Public Law. At the same time, NDA maintains very strong link with The Ministry of Education and Science according to the process of Bologna.
Germany has a unique system for civil and military education. The only true military academy is the Führungsakademie der Bundeswehr where mainly future staff officers and general staff officers are further trained.
The standard education in military leadership is the task of the Offizierschulen (officers' schools) run by the three branches. The contents differ from branch to branch. In the army all officers are at least trained to lead a platoon. There they also have to pass an officer exam to become commissioned later on.
Moreover, there exist so called Waffenschulen (school of weapons) like infantry school or artillery school. There the officers learn to deal with the typical tasks of their respective corps. A specialty of the German concept of officer formation is the academic education. Germany runs two own Universities of the German Federal Armed Forces where almost every future officer has to pass non-military studies and achieve a bachelor's or master's degree. During their studies (after at least three years of service) the candidates become commissioned Leutnant (second-lieutenant).
The three officer's schools are:
Academic and staff education:
The Hellenic Armed Forces have military academies supervised by each branch of the Armed Forces individually:
Military Schools 1. 5 Rashtriya Military Schools across India in Belgaum Belgaum Military School, BangaloreBangalore Military School, ChailChail Military School, DholpurDholpur Military School and AjmerAjmer Military School 
The Indonesian Military Academy  was founded in Yogyakarta, October 13, 1945 by the order of General Staff Chief of Indonesia Army Lieutenant General Urip Sumohardjo as the Militaire Academie (MA) Yogyakarta.
Currently, the Tentara Nasional Indonesia or the "TNI" (Indonesian National Armed Forces), under the supervision of the Commanding General of the Indonesian National Armed Forces Academy System (a three-star officer in billet) in the HQ of the Indonesian National Armed Forces, has divided the academies into the three respective services:
Each service academy is headed by a two-star general, and his/her deputy is a one-star officer. All the students (cadets/midshipman) are recruited from senior high school graduates from all over Indonesia. Shortly after graduation, they are commissioned as Letnan Dua (Second Lieutenant) in their respective services and get the Diploma IV (Associate degree, 4th Grade) comparable to civil academies or universities. The length term is now 4 years and is divided into 5 grades of cadet's rank, starting from the lowest:
Taruna refers to cadets in the Military Academy, Kadet refers to cadets in the Naval Academy, and Karbol refers to cadets in the Air Force Academy, respectively.
Until 1999, before the Indonesian National Police officially separated from the armed forces, the Indonesian Police Academy ("AKPOL") also stood under the National Armed Forces Academy but now has separated from the Military and is under the auspices of the President of Indonesia controlled by the National Police Headquarters (Mabes Polri), where in the other hand the Armed Forces (Army, Naval, and Air Force) Academies of Indonesia is under the auspices of the Ministry of Defense controlled by the Armed Forces General Headquarters (Mabes TNI). Presently, the Police Academy is located in Semarang (Central Java), and is supervised under the supervision of the Chief of Indonesian National Police (Kapolri).
All 3 academies and the Police Academy have a joint 4th class cadet training program since 2008, after completing it the cadets go to their respective academies to continue with the 3 remaining years of study before commissioning.
As of January 2018, Rear Admiral Siwi Sukma Adji, S.E.,M.M is the Commanding General, INAF Academies System, with Major General Dody Usodo Hargo, S.Ip.,M.M as the assistant commander. The Academies System was founded on 16 December 1965.
Imam Ali Officers' University (Persian: دانشگاه افسری امام علی; acronym: دا اف, DĀʿAF), formerly known as Officers' School (Persian: دانشکده افسری) is the military academy of Ground Forces of Islamic Republic of Iran Army, located in Tehran, Iran. Cadets of the academy achieve the second Lieutenant rank upon graduation and join one of Islamic Republic of Iran Army branches.

Undergraduate officer training
These colleges are operated by the Philippine Government which serves 4 years of different baccalaureate degrees:
Aside from the PMA and the PMMA, all three branches of the AFP have their own Officer Candidate Course Programs for both men and women, patterned after their US counterparts.
The nation's higher military colleges are:
The General Sir John Kotelawala Defense University, was established in 1980 and is named after Gen. Sri John Kotelawala the 2nd Prime Minister of Sri Lanka. Taking cadets from all three armed services, 3 non-university level Military Academies, one for each armed service providing basic training for officer and a Command and Staff College for senior officers of the three armed services.
Uganda maintains the followings military training institutions, as of December 2010:
A number of universities have specialized military institutes, such as the Faculty of Military Legal Studies at Kharkiv's National Yaroslav Mudryi Law Academy of Ukraine, however, the primary Ukrainian military academies are the following:
There are also numerous Cadet forces that operate for all branches of the armed forces for children aged 10–20. These are not designed to recruit people into the armed forces but rather are simply Ministry of Defence sponsored youth organisations.
Although an undergraduate degree is not a pre-requisite for Officer training, the majority of potential Officers will have attended University before joining the Armed Forces. At some universities there may be the option for people to join either a University Royal Naval Unit, a University Officer Training Corps (UOTC) or a University Air Squadron; which are designed to introduce students to life in the Forces and show them the careers that are available. People sponsored under the Defence Technical Undergraduate Scheme will join one of the four Support Units attached to universities participating in DTUS. There is a requirement for bursars of DTUS to join the military for 3 years after completion of their degree, there no requirement for students of any other organisation to join the military after they finish their degree programs; and the great majority have no further contact with the armed forces. Although service with these organisations may give some initial benefit to cadets attending the military colleges/academies, the next stage of the officer training programs assumes no prior military experience/knowledge, and those that did not partake in military activities at university are not disadvantaged.
There are now four military academies in the United Kingdom. Although the curriculum at each varies due to the differing nature of the service a man or woman is joining, it is a combination of military and academic study that is designed to turn young civilians into comprehensively trained military officers.
Officer Training for the Reserve Forces (e.g. Army Reserve, Royal Naval Reserve, RAF Reserves & Royal Marine Reserves) also takes place at the relevant military academies, but under a different curriculum and the courses tend to be concentrated into a much shorter period.
In the United States, the term "military academy" does not necessarily mean a government-owned institution run by the armed forces to train its own officers. It may also mean a middle school, high school, or college, whether public or private, which instructs its students in military-style education, discipline and tradition. Students at such civilian institutions can earn a commission in the U.S. military through the successful completion of a Senior Reserve Officers' Training Corps program along with their college or university's academic coursework.
The colleges operated by the U.S. Federal Government are referred to as Federal Service Academies and are:
There is one all-military state-sponsored military academy:
In addition, these five institutions that were military colleges at the time of their founding now maintain both a corps of cadets and a civilian student body. Many of these institutions also offer on-line degree programs:
Along with VMI, these institutions are known as the Senior Military Colleges of the US.
Today four institutions are considered Military Junior Colleges (MJC). These four military schools participate in the Army's two-year Early Commissioning Program, an Army ROTC program where qualified students can earn a commission as a Second Lieutenant after only two years of college. The four Military Junior Colleges are as follows:
There are six (6) state-operated Merchant Marine academies:
These merchant marine academies operate on a military college system. Part of the training that the cadets receive is naval and military in nature. Cadets may apply for Naval Reserve commissions upon obtaining their Merchant Marine Officer's licenses. Most if not all also offer some form of military commissioning program into the active duty US Navy, US Marine Corps, or US Coast Guard.
The United States staff colleges, mandated to serve the needs of officers for post-graduate studies and other such graduate institutions as mandated by the Department of Defense are:
Unlike other military colleges (the federal service academies), all of VMI’s students are members of the Corps of Cadets. This tradition of not offering civilian programs is in keeping with VMI efforts to offer students 'a Spartan, physically and academically demanding environment combined with strict military discipline.'
