Part of his stint in SAF would have been counted as his due diligence i think.Proof it.
Do the maths lah.
Born 1977. Educated at Victoria Sec School, then did his A levels at Victoria JC. Then joined the SAF at the age of 19 in 1996. Which means he join SAF right after A levels. So, tell me when did he find the time to do his 2 years NS? Or 2.5 years for officers in those days. Make no mistake, he is a NS defaulter.
