This is a basic border crossing scenario in which the Rhodesian Security Forces cross into Mozambique with air support and attack a guerrilla camp.
After the Mozambican War of Independence there were a lot of border squirmishes as the white Rhodesians clashed with the anti-apartied blacks who were targetting farmers and other targets.
There were a number of raids such as this between the Mozambican War of Independence on 25 June 1975 and the Mozambican Civil War in 1977.
