Willem Steenkamp, Borderstrike! South Africa into Angola 1975–1980, 3rd ed. (Just Done Productions, 2006, ISBN 978-1-920169-00-8): Alouette III shot down by an RPG-7 on 23 June 1980 during Operation Sceptic while sweeping ahead of Puma stopper groups near the Xangongo–Mongua road. Pilot Lt Tinus van Rensburg escaped on foot; Cilliers died at the wreck. Body returned to South Africa on 17 November 1982 in a prisoner exchange (with L/Cpl Wynand Swart, who is not on this roll).
5 Sep 2026: Unit "17 Squadron" (a squadron, SAAF's regiment-equivalent) promoted to Regiment, per John's decision. Corps (South African Air Force) unchanged.
25 Sep 2026, Unit2 service-branch sweep: the stored Secondary Unit "Army" was CLEARED. It was not a sub-unit, it was a service-branch word, and it CONTRADICTED this record's own Branch, "Air Force". Across the roll 787 records carried such a contradiction; judged against Corps and Regiment -- independent of both columns -- the evidence backed Branch 744 times and Unit2 not once. Branch is therefore kept and the contradicting word removed. Nothing is guessed: this man's branch of service is already recorded, and his sub-unit, if any, is simply not known.
