This research investigates the values and attitudes of military police officers regarding gender roles within the socio-political and cultural structure of the Paran? Military Police (PMPR), and consequently the absence of women in certain spaces, as well as the resistance and conflicts in relation to changes in the occupation of these almost exclusive places for one sex or the other. More than thirty years on from the entry of the first class of military police in our state, we need to ask ourselves: how are gender roles in the PMPR? In order to find answers to this and other important questions, we carried out this study, which consisted of diagnosing, by means of a survey, what military police officers think about gender roles.
