The Military Academy of Agulhas Negras (Portuguese: Academia Militar das Agulhas Negras, AMAN – named after the Agulhas Negras summit) is the biggest among several schools of formation of combatant officers 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, in the city of Rio de Janeiro. Today the Academy is located in the city of Resende, in the state of Rio de Janeiro.

In 1792, Queen Mary I of Portugal and Brazil founded the Real Academia de Artilharia, Fortificação e Desenho (Royal Academy of Artillery, Fortification and Drawing) in Rio de Janeiro, modeled after the existing Academy in Lisbon, intended to train artillery and engineering officers of the Portuguese Army in Brazil. This Academy is considered the pioneer of military and engineering education in the Americas.

The transfer of the Portuguese Royal Court from Lisbon to Rio de Janeiro in 1808 after they fled from Napoleon's invasion of Portugal caused King Dom João VI to inaugurate on 23 April 1811 the Real Academia Militar (Royal Military Academy), incorporating the previous Royal Academy of Artillery, Fortification and Drawing. Its first location was at the Artillery academy, today the location of the National Historical Museum of Brazil. In 1812, it was transferred to the São Francisco square, a place that offered better conditions for warfare maneuvers. With the Independence of Brazil in 1822, it was renamed the Imperial Academia Militar (Imperial Military Academy).

With the ever-growing need to improve the training of the officers of the Brazilian Army, it was merged with the School of War in Porto Alegre, Rio Grande Do Sul. In 1913, with the objective of uniting all the military institutes of War and Application, was created the Military Academy.

Given the urgent need to expand the facilities to serve a growing and fully operational Army, the Military School of Resende was created in the city of Resende on January 1, 1944. It was renamed the Academia Militar das Agulhas Negras in 1951.

The first female cadets of the Academy entered its doors in 2017.

The AMAN campus in Resende occupies 67 km. It contains several complexes, including the Main Complex, the Physical Education Department, the Equestrian Department, the Firearms Department and the Instruction Park. The Main Complex was expanded in 1988 to two times its original size, the expansion consisting mainly of refectories and cadets' lodgings. The Command and Services Battalion includes the Headquarters Company, a Service Company, a Military Police Company, a Guard Company, a Rifleman Company, and two Corps of Cadets Auxiliary Companies. It is the largest Battalion of the Brazilian Army.

The Cadet corps are constituted by a Commander, a Deputy Commander, a staff and diverse Courses and peculiar Sections, composites for Officers and Cadets with the diverse missions and characteristics. Specialties include infantry, cavalry, artillery, combat engineering, communications, quartermaster, and ordnance.

Cadets receive training in riding, weaponry, and physical fitness.

Just like so many military academies in the world, the AMAN is a medium-sized, highly residential baccalaureate college, with a full-time, four-year undergraduate program that emphasizes instruction in the arts, sciences, and professions with no graduate program, preparing men and women to take on the challenge of being officers of the Brazilian Army.

A cadet's career begins at the Preparatory School of the Brazilian Army (Escola Preparatória de Cadetes do Exército), where they complete an initial year of military studies. Later, they should attend the Academy where another year of basic formation training takes place. The next period, qualification, lasts from the second to the fourth year.

In the first period, the cadet's personality is adjusted to military life and combat. The cadet undergoes physical qualification and training in various abilities. During the second period, the cadet practices command, continues with physical training and develops to meet the positions and functions of subordinate officer and captain.

Other activities include maneuvers, the Academic Olympics, sporting competitions against the Naval School and the Academy of the Air Force (NAVAMAER) and the South American Festival of Cadets.

The academic program consists of a structured core of subjects depending on the cadet's chosen specialty as a future Army officer, balanced between the arts and sciences. In the first year the cadets receive common education in various subjects and from the second year onward studies depend on the specialty branch he or she will be posted after graduation. Regardless of major, all cadets graduate with a Bachelor of Military Science degree.

As all cadets are commissioned as aspirants upon graduation, military and leadership education is nested with academic instruction. Military training and discipline fall under the purview of the Office of the Commandant of Cadets. After the preparatory period in the EsPCEx, the New Cadets join the ranks of the Corps in February every year. Each New Cadet receives strict military training as part of his/her first year in the academy, including physical training and arms training. They are recognized as full cadets in a ceremony in August where they receive ceremonial daggers, similar to those used by the Duke of Caixas, whilst wearing the blue dress uniform of the Corps. During the summer, the fourth class cadets spend their vacations in the specialty branch school of their choice, beginning the second year as full fledged third class cadets of their chosen service branches within the Army:

• Infantry Branch
• Armored Cavalry
• Field and Air Defense Artillery
• Corps of Engineers
• Signal Corps
• Logistics
• Materiel

In addition to the tough physical training regime and weapons training, each of the cadets are trained to endure the tough environments of the country in the performance of defense and security operations, as well as in assisting law enforcement and in peacekeeping duties abroad. During the Brazilian spring, all cadets go towards one year-end training exercise to assess their skills and apply the lessons learned during their studies.
