Amin in 1946 joined the King's African Rifles, a British colonial regiment, serving in Kenya and Uganda. Eventually, Amin held the rank of major general in the post-colonial Uganda People's Defense Force and became its commander before seizing power in the military coup of January 1971 that deposed Milton Obote. While he was head of state, he promoted himself to field marshal.  - The Ugandan Bush War (also known as the Luwero War, the Ugandan civil war or the Resistance War) refers to the guerrilla war waged between 1981 and 1986 in Uganda by the National Resistance Army (NRA) under the leadership of Yoweri Museveni against the government of Milton Obote, and later that of Tito Okello.  - Apollo Milton Obote (28 December 1925  10 October 2005) was a Ugandan political leader who led Uganda to independence in 1962 from British colonial administration. Following the nation's independence, he served as Prime Minister of Uganda from 1962 to 1966 and President of Uganda from 1966 to 1971, then again from 1980 to 1985.

It performed both military and internal security functions within the colonial territory, and later served outside these territories during the World Wars. The rank and file (askaris) were drawn from native inhabitants, while most of the officers were seconded from the British Army.
