Van Heerden , Johannes Jacobus (J J)

SN CORRECTION 25 Aug 2026: ServiceNo 66566647E cleared -- the pantser.cmvo.org.za SADF deaths PDF lists that number under "VAN HEERDEN, JOHANNES HENDRIK" (LT, Sterf 07 01 69), matching PersonNumber 33523 (Van Heerden, DateDeath 1969-01-07) by surname and exact date, not this record. Original value: "66566647E". Left as an unresolved collision otherwise -- this correction is specific to this one PDF-confirmed case, not a general claim this record's other data is wrong.
5 Sep 2026: Unit "40 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.
