Yes, i know Chay W C in A Coy. In fac,t he was in my platoon. Yes, I know Neo Keng Kok, later became CPT and also became OC of Parachute School.
Do you know Alan Lee Sian Ghee, frm A Coy? No, I was not from 8 SIR and did not go there after SMC, I was from 4 SIR.
Ananda Raja was in B Coy, he later became an Assof Prof of Sociology at NUS. I met him in NUS and was surprised that he was from 4 SMC too, but I never met him personally at OCS. Only years later, I studied under him. He passed away when he was 54 years old in his office at NUS. He was such a humble an intelligent person.
Ko Chee Wah was in the same platoon as me. The day I saw him I knew that he would be the sword of honour. Showed strong leadership, and he dared to be outstanding.
I met Chay when we were at HQ 2SIB (perhaps, your men, if they have performed guard duties at HQ 2SIB, may have told you about a "garang" officer from HQ 2SIB). He was DY S1. Although I have been away for about 30 yrs, he and I have kept in touch, and we meet everytime I am in Singapore.
If you were from 4 SMC, and thereafter went to 4 SIR, your CO could be Major Neo Poh Chuan or Major Chow Giak Piak (not sure who is 3 SIR or 4SIR, but both from first batch OCS).
Several years ago, when I was in SG, I contacted Neo Keng Kok, through his daughter (after my earlier attempts to contact him and leaving messages, through his father). He went into the landscaping business.
