I cannot speak much for Charlton..but all Camden County Public Safety agencies are dispatched by Camden County Sheriffs Office 911 Communications Center, including all county/city law enforcement and fire/rescue. Camden County Fire/Rescue provides EMS services county-wide, including in the cities of Kingsland, St.Marys, and Woodbine. CCFR also provides fire protection services for the unincorporated areas of the county and the city of Woodbine. The cities of Kingsland and St.Marys have their own Police and Fire Departments, Camden County Sheriffs Office has jurisdiction county-wide..but mainly patrol and respond to calls for service in the unincorporated areas of the county and the City of Woodbine. in the Cities of St.Marys and Kingsland.. Camden County Fire/Rescue, St. Marys Fire Dept., and Kingsland Fire/Rescue respond as one. a normal fire/rescue response in both cities is one Camden County Fire Rescue ambulance or "Life Squad" and one St.Marys FD Engine in St.Marys or in Kingsland, one Camden County Fire Rescue ambulance or "Life Squad" and one Kingsland Fire Rescue Engine. a list of Camden County Fire Rescue station locations can be found on the county website at this link
