The military man who occupies a central position in Brazilian aerospace defense is called “anti-aircraft defense lessor”. In this operational routine, tasks of great complexity and responsibility are implicit, demanding attention and emotional control. However, these features are insufficiently described. Therefore, the aim of this study was to verify the personality and attention profile of air defense contractors. The main results indicate that there are characteristics of the personality profile of “anti-aircraft defense lessors” more evident than their peers with functional performance in other technical areas. Although the “anti-aircraft defense lessors” have attention performance similar to the control ones, it was found that the length of service progressively influences the participants' attention performance in a negative way. These findings can serve as guidelines for future studies of staffing strategies as well as methodologies for improving care processes.
