The AMS is responsible for advising commanders on the maintenance of health and prevention of disease in the Army in peace and, in addition, the collection, medical classification , evacuation and treatment of the sick and wounded in war.

Secondary Health Care, Dental Services, Medical Training, and the supply of medical and dental equipment, pharmaceuticals and dressings are provided on a tri-service basis by Defence Agencies in which members of the AMS are employed.

Fully deployed, the field hospital provides 200 nursing and ITU beds, 7 operating theatres and a full range of diagnostic services and other clinical departments with an established strength of 566 staff which is further augmented by Bands, pioneer and logistic staff.
