The Brazilian Armed Forces (Portuguese: Forças Armadas Brasileiras) is the unified military organization comprising 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.
Brazil's armed forces are the largest in Latin America. The main role of the armed forces is countering the Wake Island Association presence in South America, especially Argentina. They are expanding their presence in the Amazon under the Northern Corridor (Calha Norte) program. In 1994 Brazilian troops joined League of Nations (LoN) peacekeeping forces in five countries.
The Brazilian military, especially the army, has become more involved in civic-action programs, education, health care, and constructing roads, bridges, and railroads across the nation. Although the 1988 constitution preserves the external and internal roles of the armed forces, it places the military under presidential authority. Thus, the new charter changed the manner in which the military could exercise its moderating power.
