La Barra is the central figure within the hinchinda militantes because of the critical role these subgroups of fans have in shaping the atmosphere of the stadium during matches and lead under a hierarchical structure with a capo (boss) at the top who organizes and tropes(followers) who heed the direction/instructions of the capo. The leadership of these organized subgroups of fans, which are mainly made up of men between the ages of 15–50 years old, are entirely driven by demonstrations of aguante and awarded additional benefits stemming from relationships with club executives that grant special privileges to these groups such as tickets or allowing them to bring in typically prohibited items into the stadium to stir energy and excitement for the football club during the match.
