He held various positions in the army, including head of the National Leadership Academy, and served as a brigadier during the Uganda–Tanzania War of 1978 and 1979.

[1] While there he served as chairman of Northcote Hall,[3] and in 1962 he performed in the first showing of Ngũgĩ wa Thiong'o's play, The Black Hermit, at the Ugandan National Theatre.

[6] From 1971 to 1974 Lupogo was Commandant of the TPDF's Officer Cadet School and from 1974 until 1976 he acted as the Tanganyika African National Union's assistant secretary for defence and security.

The TPDF embarked on a programme of expansion and in January 1979 Lupogo acted as a recruitment officer at the military camp in Makambako.

When Tanzanian commanders feared that a Ugandan regiment was due to attack them from Mubende, they dispatched Lupogo and his brigade north from Masaka to intercept it.

Their efforts were unsuccessful and Tanzanian morale steadily dropped until TPDF commanders decided to withdraw Lupogo and replace him with Brigadier Muhiddin Kimario.

[5] Following the end of his military service, Lupogo acted variously as the Regional Commissioner for Iringa, Director General of the Arusha International Conference Centre, and Board Chairman of the Benjamin Mkapa Foundation.
