This thesis aims the officers of the Brazilian Army. More precisely, the process in which young yet imbued of current values in the civil society, when joining military institutions, they become, gradually, in spokesperson of these institution s values, starting to belong and serving them. To carry out the proposal, we will perform the comparison between three groups of officers from the Brazilian Army: Agulhas Negras Military Academy (AMAN, from Portuguese, Academia Militar das Agulhas Negras), the Temporary Officer Technicians (OTT, from Portuguese, Oficiais Técnicos Temporários) and the ones who belong to the Complementary Officers Team (QCO, from Portuguese, Quadro Complementar de oficiais). The hypothesis is that these three Officer groups show some difference when confronted with social, political, ethical and institutional contents of the Brazilian national life because of possible differences in their mindset, carreer strategies, interests and world perspective. Posture that will allow us to suppose not only about the called total institutions but also about the isolation patterns of the Brazilian Army Officers. The way we decided to trace and analyze the possible differences between these type of Officers lies on the Survey What the Officer of the Brazilian Army think coordinated by the Professors Eduardo Raposo and Maria Alice Resende de Carvalho, both from the Department of Social Science at PUC-Rio and also by the Professor Sarita Lea Schaffel from CEP/Brazilian Army.
