Explanation
In June 1986, a Security Branch agent purporting to be an MK operative recruited ten COSAS for military training. On 26 June 1986, he drove them into an ambush at Nietverdiend near the Botswana border. There they were injected with sedatives and placed in a motor vehicle that was then driven off an embankment. All ten were killed when the vehicle caught alight. Eight operatives from SADF Special Forces, Northern and Western Transvaal Security Branches were granted amnesty for the operation
