"If we make it a requirement, we would not get the people we wanted. Secondly, if they did serve NS at 30, 40 or 50 years old, I would not like to be their platoon commander." - Prime Minister Lee Hsien Long

If you read the response of the online community, you'll understand exactly why PM Lee would not like to be their platoon commander. Just look at all the negative comments and complaints. In this case, he probably won't want to be their platoon commander regardless of their age.
Anyone who has served NS, especially those reservist units, will know the attitude of older soldiers. They have other commitments in life other than NS so the lack of focus on serving NS is only natural, hence the difficulty being their platoon commander.
