Wah biang.. one thing that irks me is that my C9L2 friends
happily made their way through to become some technician, clerk or
storeman or whatever stay out vocation. And being a L9, I'm posted
to some stay in unit, drawing some combat pay.
Quoting from NS.sg
"C9 - No IPPT, L9 - Suitable for peacetime sedentary duties
at Bases. Not fit for operational duties even in Bases"
So why me? 
Maybe I'm illiterate or somehow manage to misinterpret
the medical directive; but anyhow... the next time anyone cites to
me any directive at all, I'd be utterly amused.
