The regiment left the UK and joined Allied Force Headquarters in North Africa.
By mid-March 1943 it was deployed around Bone in Algeria and Tabarka in Tunisia under 66th AA Brigade.
Bone was under regular air attack and 66th AA Bde had little early warning of attacks, as a result it 'was being hammered'.
By the culmination of the campaign, in May, 84th HAA Rgt had been transferred to  52nd AA Brigade and was 'on its wheels ready to move to Tunis and Bizerta, immediately behind the leading battle groups' of Operation Vulcan.
When the Axis forces surrendered, it was in the process of deploying in Bizerta, which was designated an 'Inner Artillery Zone' for air defence.
