The Brazilian Armed Forces (Portuguese: Forças Armadas Brasileiras, IPA: [ˈfoʁsɐz ɐʁˈmadɐz bɾaziˈlejɾɐs]) 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.



Brazilian Army History:



As in most South American nations, the Brazilian Army (Portuguese: Exército Brasileiro, [ɛˈzɛʁsitu bɾaziˈlejɾu]) has been the most influential of the services because of its size, deployment, and historical development. Not only did senior army generals occupy the presidency from 1964 until 1985, but most of the officers who held cabinet posts during that time were from the army. In 1997 the army totaled 200,000 members. Brazil's army has strict up-or-out retirement rules, which were developed in the mid-1960s by President Castelo Branco. The internal command structure determines all promotions through the rank of colonel. The president is involved in the promotions to general and chooses one candidate from a list of three names presented to him by the High Command. Once passed over, the colonel must retire. All colonels must retire at age fifty-nine; and all four-star generals must retire at age sixty-six, or after 12 years as general.

Despite the up-or-out system, under President José Sarney the army became top-heavy as generals began to occupy many positions that previously had been reserved for colonels. In 1991 there were 15 four-star, forty three-star, and 110 two-star generals. The figure for four-star generals did not include four who were ministers in the Superior Military Court (Superior Tribunal Militar-STM). Thus, in the mid-1990s the army sought to reduce the number of active-duty generals. Considering the short conscript tour (usually nine to ten months), the army has a high number of conscripts: 125,000. Because of the need for literate and skilled young men to handle modern weapons, the army has served as a training ground for a large reserve force. Its highly professional officer corps serves as a nucleus around which the trained service would be mobilized if required.



The noncommissioned officer (NCO) corps is not well developed. NCOs have virtually no autonomy or authority. Emphasis on training and professional development is for officers only. The NCOs account for slightly more than one-third of the total army strength. About half of the NCOs are sergeants, who serve as command links between officers and ranks. Some also serve as middle-level technicians. In the early 1990s, the army began to undergo a generational change. The generals of the early 1990s had been junior officers in the early 1960s and had witnessed the military coup in 1964. Their worldview was shaped and influenced by the anticommunism of that time. These generals were being replaced by colonels who had entered the army in the early 1970s and whose view of the world had been shaped less by ideology and more by pragmatism. The United States, particularly through its counterinsurgency doctrines of the early 1960s, was more influential with the older group of officers.


Caatinga Information:


Caatinga (Portuguese pronunciation: [​ka.ɐˈtʃĩɡɐ], locally [​ka.aˈtĩɡɐ]) is a type of subtropical vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" is a Tupi word meaning "white forest" or "white vegetation" (caa = forest, vegetation, tinga = white).

The Caatinga is a xeric shrubland and thorn forest, which consists primarily of small, thorny trees that shed their leaves seasonally. Cacti, thick-stemmed plants, thorny brush, and arid-adapted grasses make up the ground layer. Most vegetation experiences a brief burst of activity during the three-month long rainy season.

Caatinga falls entirely within earth's tropical zone and is one of 6 major ecoregions of Brazil. It covers 850,000 km², nearly 10% of Brazil's territory. It is home to 26 million people and over 2000 species of plants, fish, reptiles, amphibians, birds, and mammals.

The Caatinga is the only exclusively Brazilian biome, which means that a large part of its biological heritage cannot be found anywhere else on the planet.
