WO can be NSmen, but of course not NSF, there's not enough time
to promote.
Most NS units' CSM, RSM, BSM, etc. are all NSmen who were never
regular in their life., but it takes at least 7 - 10 years of NSman
service to promote to WO.
Really respect them, most of them volunteered to go for all the
courses, and to go back ICT earlier and beyond their normal duty to
serve the rest and make sure everyone is ok, same as NSmen RQMS
who're also WO.
Just 1-2 yrs ago, all CSM were regular SSG and above, nowaday
notice that now got NSF CSM also, but hold 2SG rank? They will be
those who will go thru all the courses and slowly promote in NSman
lifetime.
