The Zimbabwe Defence Forces were set up by unifying three insurrectionist forces – the Zimbabwe African National Liberation Army (ZANLA), the Zimbabwe People's Revolutionary Army (ZIPRA), and the Rhodesian Security Forces (RSF) – after the Second Chimurenga and Zimbabwean independence in 1980. The integration period saw the formation of the Zimbabwe National Army (ZNA) and Air Force of Zimbabwe (AFZ) as separate entities under the command of Rtd General Solomon Mujuru and Air Marshal Norman Walsh who retired in 1982, and was replaced by Air Marshal Azim Daudpota who handed over command to Rtd Air Chief Marshal Josiah Tungamirai in 1985.
