There is no known national leader of the Bloods but individual Bloods sets have a hierarchical leadership structure with identifiable levels of membership. These levels of membership indicate status within a gang. A leader, typically an older member with a more extensive criminal background, runs each set. A set leader is not elected but rather asserts himself by developing and managing the gang's criminal enterprises through his reputation for violence and ruthlessness and his charisma. The majority of set members are called "soldiers", who are typically 16 to 22. Soldiers have a strong sense of commitment to their set and are extremely dangerous because of their willingness to use violence both to obtain the respect of gang members and to respond to any person who "disrespects" the set. "Associates" are not full members, but identify with the gang and take part in various criminal activities. To the extent that women belong to the gang, they are usually associates and tend to be used by their male counterparts to carry weapons, hold drugs, or prostitute themselves to make money for their set.
