The G6 was deployed by expeditionary units of the South African Defence Force during the Angolan Civil War, making its combat debut during Operation Moduler in December 1987. South African artillery observers, sometimes working behind enemy lines, did not hesitate in making full use of the howitzer's pinpoint accuracy. On one occasion reconnaissance elements observed Angolan interceptors attempting to take off from an airfield near Cuito Cuanavale and immediately requested artillery support; in a single bombardment G6s succeeded in eliminating four Mikoyan-Gurevich MiG-21s on the ground.
