Mpumelelo Hlubi was sentenced to 15 years for the murder of Lieutenant Thabiso Seithati, 28, and to 10 years for the murder of Gunner Zakhe Khumalo, 26, said Sergeant Majang Skalkie. The sentences would run concurrently.
In February, Hlubi shot Seithati and Khumalo while driving from the Fouriesburg military base to the Kromdraai temporary base, near the Lesotho border, in a military vehicle.
Hlubi dumped their bodies beside the Kromdraai farm gravel road.
An R4 rifle and a cellphone were taken from the men and were later found with Hlubi.
