This thesis investigates the process of identity construction of paratrooper officers serving the Brazilian Army with special attention to narratives of life history. The corpus of data was generated through interviews carried out by the researcher with 10 paratrooper officers stationed in the 26th Parachute Infantry Battalion , besides another interview with an officer who had served in the battalion. Taking a vision of speech as a form of social action; identity as a socioconstructed, relational, dynamic, situated, fluid, contextual and procedural phenomenon; narrative as a situated construction of the experience, guided by the narrator s affective filters through which he/she organizes his personal experience inscribed in the social order, the investigation focused at the processes of identities construction of individuals who practice, experience and share a code of values in a particular context: the paratrooper community of the Brazilian Army. Also, the researched aimed at understanding how the paratroopers make use of such values to develop parts of their autobiographies taking into account the contemporary scene in which their lives occur. The focus of the analysis rests on the dynamics between social and individual agency, enabling the dialogue between the social context and subjectivity. In the analysis, special attention was given to the construction of the point of such narratives, as well as the instantiation of evaluations and resolutions. In turn, these narratives are responsible for building the paratrooper set of beliefs, once they repeatedly reaffirm and sustain the values shared among the community studied. The researcher discussed the coercive forces of the group in the construction of collective identities of its members and how these forces require performances of identity at the same time that they provide group members with both a sense of belonging and the security of believing knowing who they are. It was noticed that among the coercive forces active in the paratrooper community, marked mainly by the evidence of the physical, emotional and moral attributes valued in that ecology, that the act of narrating and summing up past experiences and achievements rises a sense of self, expressed vividly by the narrators in the stories they tell. The paratroopers are built as main and heroic characters in their own narratives. This notion of socioconstructed self was understood as a dramatic effect arising from the narrative action. It is during the sociointeractional performance, that is, the vivid and pulsating narrative scene, that the paratroopers show ontological sensations and existential feelings, understanding themselves as professionals driven by the paratroopers’ ideals whose attributes of superiority, they say, are intended to their most precious possession, the latter understood by paratroopers as the unconditional willingness to defend and maintain national integrity.
