Officer cadet in the context of University Service Units

A military academy or service academy 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-collegiate-level institutions awarding academic qualifications, university-level institutions awarding bachelor's-degree-level qualifications, and those preparing officer cadets for commissioning into the armed services of the state.

The Military Academy of Agulhas Negras (Portuguese: Academia Militar das Agulhas Negras, AMAN) is a service academy for training of officer cadets of the Brazilian Army. It originated in 1792 with the creation of the Royal Academy of Artillery, Fortification and Drawing, the first military school of the Americas. It is located in Resende, in the state of Rio de Janeiro.

It is the only institution that trains career officers in the Infantry, Cavalry, Artillery, Engineering and Communications branches, as well as the Ordnance Corps and the Army Quartermaster Corps.

The Royal Military College of Canada (French: Collège militaire royal du Canada), abbreviated in English as RMC and in French as CMR, is a military academy and, since 1959, a degree-granting university of the Canadian Armed Forces. It was established in 1874 and conducted its first classes on June 1, 1876. Programs are offered at the undergraduate and graduate levels, both on campus as well as through the college's distance learning program via the Division of Continuing Studies.

Located on Point Frederick, a 41-hectare (101-acre) peninsula in Kingston, Ontario, the college is a mix of historic buildings and more modern academic, athletic, and dormitory facilities. RMC officer cadets are trained in what are known as the "four pillars": academics, officership, athletics, and bilingualism.
