Each DNACO has a specific set of operational areas he or she is responsible for, with one or more of the appointed Assistant National Commodores (staff officers) reporting in. Additionally, each of the three elected DNACOs (O, RBS, and MS) are the reporting point for approximately one third of the 16 District Commodores, grouped by geographical area, who are elected every two years to lead their local membership.
