The Zambia Army is the land military branch of the Zambian Defence Force. The Zambia Army comprises the Regular Force, Home Guard and the Territorial reserve which is charged with defending the territorial integrity of Zambia from internal and external aggression. Like all branches of the Zambian military, citizens of the nation are required to register at 18 years old when they are classified as adults in Zambia. Applicants to join the Zambia Army must be Zambian citizens, holder of a green national registration card and must have a school Grade 12 certification.
The Zambia Air Force (ZAF) is the air operations element of the Zambian Defence Force. Following Zambia's independence in 1964, the Northern Rhodesia Air Force was renamed the Zambia Air Force. The primary role of the Air Force is to defend Zambia's borders/assets and the Zambian air space. Furthermore, the Air Force provides air support to other government departments, flies reconnaissance, trooping and transport missions, and airlifts medical supplies and personnel to inaccessible areas.
The Zambia National Service (ZNS) is part of the Zambian Defence Force. It's main objectives revolve around land development, agriculture, industries, youth skills training as well as arts, sports and culture. It was established in 1963 as Land Army and was used as a militant wing of an indigenous major political party fighting for Zambia's independence at the time. It was later renamed the Zambia Youth Service in 1965, however, due to escalating liberation wars in the region, the Government felt the need for a more militant organization to augment the Zambia Army.
