The only SAF personnel who is a true blue professional soldier is Colonel Lo Yong Poo, former CO of SISPEC and Commander of BMTC. He was one of the heroes in the SQ hijacking incident, as he was one of the SOF commandoes who eliminated the terrorists and salvaged the situation.
Unfortunately, he was not considered for promotion to a General rank, and was given various non-operational appointments (such as those training schools) due to the fact that his highest educational qualification was O Levels.
During his time in the SAF, he was regarded as a true-blue professional soldier. He attended the US Marines course and topped his class at the age of almost 40, outperforming the much younger American trainees. Moreover he also was well-known for having an SOC timing of under 6:30 even though he was much older than most recruits. He was a man of no airs, constantly talking to recruits in BMTC and asking for their feedback. He led by example and many of his men commented that they would be willing to go to war with him. He was held in the utmost respect by anyone who worked with him.
Unfortuantely, SAF does not promote people based on their military capabilities but their academic results. If Lee Hsien Loong, Lui Tuck Yew, Chan Chun Sing and the fat retard Ng Yat Chung can be generals, please don't tell me that Lo Yong Poo is not cut out to be a general?
He obviously took an early retirement and left to join the private sector where he is now the CEO of Goodrich which is a well-known textiles firm. He is one of the VERY FEW ex-military men who actually managed to make it in the private sector with HIGHER PAY than his public sector job. Instead of taking a role in a GLC or stat board, he proved that he could make it in the private sector where there is no place for wayang and full spotlight is on results.
