The existence and mandate of the Zimbabwe Defence Forces (ZDF) is enshrined in the Constitution of Zimbabwe. The ZDF was set up by the integration of three belligerent forces, the Zimbabwe African National Liberation Army (ZANLA) and the Zimbabwe People’s Revolutionary Army (ZIPRA) on one side and the Rhodesian Security Forces (RSF) on the other, at the end of the War of Liberation in 1980. The integration period saw the formation of the Zimbabwe National Army (ZNA) and Air Force of Zimbabwe (AFZ) as separate entities.
