I know of old buddies who are friends with LHY, and went to "play" at his parents' house at Oxley Road when they were at NJC. Those fellas went to the "Scholars Platoon" in Charlie Company, 3 SMC, OCS, SAFTI.
Let me attempt to re-construct the time line: enlist for NS on Dec 26, 1975, then on SAFOS (and he was also a President's Scholar) to UK in 1976, say graduate in 1980, returned to SAF as LTA, promoted to CPT in 1981, promoted to MAJ in 1983. Based on the other prior messages, it is logical and reasonable that he would have been a MAJ when he was the CO at 46 SAR.
Was 46 SAR a tank battalion or AI battalion?
Does any one recall whether or not LHY attended any overseas Armour Officers Course?
Did he attend SCSC in Singapore or a Command and Staff College overseas?
