We're here to help - A Scout District is run by:
DC - District Commissioner - who co-ordinates everyone else;
ADCs [Assistant DCs] for Beavers, Cubs, Scouts - who co-ordinate all the Beaver Colonies, Cub Packs, & Scout Trooops in the District;
ESC [Explorer Scout Commissioner] - who co-ordinates all things Explorer Scouting;
DSLs [District SLs], DBSLs [District Beaver SLs], DCSLs, & DESLs - who help the ADCs.
For County level, substitute C [County] for D in the above.
