Yes, he got discount. Such discount is illegal, and not permitted under the Enlistment Act.
I don't care how long eat shit has spend the SAF. That was not the point. The point was he never completed NS. That is 2 separate issues.
I have already mentioned Patrick Tan did not complete his NS. Read the earlier posts. Patrick Tan enters NS and first 3 months in BMT scholar platoon. Was this 3 months real NS. Yes, he received NS pay and allowance and subject to same rules as other recruits. Patrick Tan then went to OCS, from my understanding, only for 2 weeks before deferring to go for his studies. Was this first 2 weeks also real NS. Yes. After that, no more NS for him. He was given expensive and long education under scholarship. Also paid as a regular when he returned.
