Just check your ns booklet at ns.sg. It will show. As long got saf100 issue are consider as call up. Half day event also count as low key.
Your clerk is wrong lah. Need at least 7 Hk n ten call up in total. So can be 7 Hk 3 lk or 8 Hk 2 lk n must fulfill 10 work years. If on one work year call up two times consider as one only.
You confirm mr Liao cos u got that final 3 k.
Eh.. Bro .. not correct wor. Maybe becoz my NS Men period spread to 12 years (Somewherer between Nov 1998 to Nov 2010).
I MRed with only 7 High + 1 Low Keys + 12 Years.
When I got my 7 High, I even called back my unit to ask when would I be called back to fulfill the 2 remaining Low Keys. My WO told me our unit
no longer has any Low Keys and I might have to serve extra High Keys to fulfill the 10 ICTs requirements which I was "LL" but no choice had to wait for additional High Key call-up than received the letter telling me I have completed my ORNS and is placed to MR Reserves.
