What position in a hierarchical system does lieutenant imply? Would a gang use the system and assign children to #1 positions?
Lieutenant
Lieutenant the second junior-most or in some cases the junior-most commissioned officer in the armed forces, fire services, police, and other organizations of many nations. Many gangs use military rankings to describe their internal heirarchy. Many young children are inducted into gangs with heirarchies. Children can grow up to be whatever they want to be.
