This study consists of an effort to investigate the role of the Brazilian Army throughout the constituent moment (1985)(1986)(1987)(1988). In a context of the transition from the military to a liberal-democratic regime, we understand that the military's departure from the political stage did not mean a real return to the barracks, but a backstage retreat. The military inserted itself into the arena of disputes that was the constituent process, participating in it according to the pre-defined rules of the democratic game. In this sense, the highest authorities of the Brazilian Army demanded constitutional prerogatives of corporate interest from the National Constituent Assembly (NCA). In the form of lobbying, speeches and threats, the weight of the military bureaucratic apparatus pressured the Constituents to approve their demands. Therefore, we sought to understand and list the main objectives of the military institution, analyzing the content of its demands, as well as its relationship with the official military memory about the coup of 1964and the dictatorship that was forged during the democratization process. It is worth noting that we deepened this study based on the assumption that the Army is not a monolithic institution. We approached civil-military and intra-military relations with the objective of understanding not only the challenges and obstacles of the institution's official objectives, but how the military demands to the Constituent were socially hegemonic. For this reason, we followed the unfolding of some themes of military interest in the NCA: the constitutional destination of the Armed Forces; the non-extension of amnesty; the noncreation of the Ministry of Defense; the maintenance of obligatory military service; the subordination of the military police to the Army; the political rights of the military; the National Security Council; and the constitutional protection of the rank of officer of the Armed Forces. We maintain that the success of the castros' claims did not necessarily mean a simple continuation of authoritarian devices in a democratic Constitution, but rather as the result of a political process marked by conciliation and accommodation of interests of the political elites and the military dome. Fundamentally, military prerogatives were re-signified, that is, they received new clothes suitable for the new liberal-democratic regime that was taking shape.
