Pardon me, but 23SA was not in Taman Jurong Camp. Only 4 camps over there, Sch of Arty, 22SA, 24SA n Arty HQ. 23SA was in Katib Camp. Before promoted, he (Lta) served a stint in 20SA (Sungei Kadut) as BC.
Year '74, LHL was a captain then attached to Arty HQ. Colonel Gill was the Chief of Arty then.
Later, BG Lee reported to COL Gill, when they were both at MINDEF.
