The duties of AMS can be divided into emergency and general duties. In times of emergency and natural disaster, AMS will supplement the medical and health services by providing triage/treatment to the injured on the spot, to convey casualties to hospitals, and to care for patients at both acute and convalescent hospitals. With its teams of uniformed members trained in ambulance manning techniques and first aid, AMS also reinforces the regular ambulance services and provides first aid coverage at public functions.
