The objective here in was to get acquainted with the contemporary students of Colégio Militar do Rio de Janeiro (CMRJ), in their relation with the uniforms, the insignia, the language and the private gestures of the Brazilian Army, considering that the respective Armed Force makes use of these identity items to reproduce its military spirit. The research methodology used was the Actor-Network Theory (ANT), by Latour, and we also worked with Foucault s notion of device (dispositif), revisited by Agamben. On the strategy of following the actors, the adjustments, the reinterpretations and the resignifications were identified by means of what the students share at school, in the same way it was observed the way the military institution itself contributes to this process.
