Tiger Hong was commissioned as a LTA, not CPT. In SAFTI, he was S4 OCS in 1979. I know because he was often the DOO when I was on guard duty at SAFTI.
Yes you are right....he was commissioned circa 76-77.
Back then OCS S4 was called LGO.
Another famous name there during that time was PC Tommie Goh.....then also Lta rank.
Din remember Morries probably before my time.
