Consisting of three service branches, it comprises the Brazilian Army (including the Brazilian Army Aviation), the Brazilian Navy (including the Brazilian Marine Corps and Brazilian Naval Aviation) and the Brazilian Air Force (including the Aerospace Operations Command).

Brazil's armed forces are the second largest in the Americas, after the United States, and the largest in Latin America and the Southern Hemisphere by the level of military equipment, with 334,500 active-duty troops and officers. Brazilian soldiers were in Haiti from 2004 until 2017, leading the United Nations Stabilization Mission (MINUSTAH).

Organization
The Armed Forces of Brazil are divided into 3 branches:
 Brazilian Army
Brazilian Army Aviation Command
 Brazilian Navy
Brazilian Marine Corps
Brazilian Naval Aviation
 Brazilian Air Force
Aerospace Operations Command

The Military Police (state police) alongside the Military Firefighters Corps are described as an auxiliary and reserve force of the Army. All military branches are part of the Ministry of Defence.

The Brazilian Navy which is the oldest of the Brazilian Armed Forces, includes the Brazilian Marine Corps and the Brazilian Naval Aviation.

Service obligation and manpower
18–45 years of age for compulsory military service; conscript service obligation – 10 to 12 months; 17–45 years of age for voluntary service. An increasing percentage of the ranks are "long-service" volunteer professionals; women were allowed to serve in the armed forces beginning in the early 1980s when the Brazilian Army became the first army in South America to accept women into career ranks; women serve in Navy and Air Force only in Women's Reserve Corps.

Mission and challenges
South America is a relatively peaceful continent in which wars are a rare event; as a result, Brazil hasn't had its territory invaded since 1865 during the Paraguayan War. Additionally, Brazil has no contested territorial disputes with any of its neighbours and neither does it have rivalries, like Chile and Bolivia have with each other. However, Brazil is the only country besides China and Russia that has land borders with 10 or more nations. Moreover, Brazil has  of land borders and  of coastline to be patrolled and defended. Overall, the Armed Forces have to defend 8.5 million km2 (around 3.2 million sq. mi.) of land and patrol 4.4 million km2 (around 1.7 million sq. mi.) of territorial waters – or Blue Amazon, as the Brazilian Navy calls them. To achieve this mission, significant manpower and funding is required.

Military history of Brazil

Since 1648 the Brazilian Armed Forces have been relied upon to fight in defense of Brazilian sovereignty and to suppress civil rebellions. The Brazilian military also has three times intervened militarily to overthrow the Brazilian government.

The Brazilian Armed Forces were subordinated to the Emperor, its Commander-in-Chief. He was aided by the Ministers of War and Navy in regard to matters concerning the Army and the Armada, respectively. Traditionally, the Ministers of War and Navy were civilians but there were some exceptions. The model chosen was the British parliamentary or Anglo-American system, in which "the country's Armed Forces observed unrestricted obedience to the civilian government while maintaining distance from political decisions and decisions referring to borders' security".

The military personnel were allowed to run and serve in political offices while staying on active duty. However, they did not represent the Army or the Armada but instead the population of the city or province where elected. Dom Pedro I chose nine military personnel as Senators and five (out of 14) to the State Council. During the Regency, two were chosen to the Senate and none to the State Council as there was no Council at the time. Dom Pedro II chose four military personnel to become Senators during the 1840s, two in the 1850s and three until the end of his reign. He also chose seven military personnel to be State Counselors during the 1840s and 1850s and three after that.

It has built a tradition of participating in UN peacekeeping missions such as in Haiti and East Timor. Below a list of some of the historical events in which the Brazilian Armed Forces took part:
