Following Rhodesia's reconstitution and recognised independence as Zimbabwe in 1980, the Grand Cross of Valour was awarded to Major Grahame Wilson, He was the second and final person to be awarded the honour after Chris Schulenburg, who received the award while serving with the Selous Scouts.
During Rhodesia's transition to Zimbabwe, Wilson obtained the rank of Major and retired after serving as Officer Commanding Special Air Service from April 1980 to the unit's disbandment in December that year. He delivered the final regimental address at Kabrit Barracks on December 13 1980, before the final lowering of the colours. An account of the role of the SAS in the Rhodesian Bush war was authored by Major Wilson and Greg Mills, entitled "Who Dares Loses: Assessing Rhodesia's Counter-Insurgency Experience".
