I don't think so, not to my knowledge. Certainly not via the
bureaucratic-promotion method, though I do recall this NCO who got
an on-the-spot "battlefield" commission during the Hotel New World
Collapse (for his ad-hoc manpower organization on the ground). It
was mentioned in the papers.
MINDEF seems to have concrete plans to expand the capacity of the
WOSE Corps though, under the 3G Army umbrella. From their
website:
"Over the years, the job responsibilities of the WOSEs have
expanded beyond the traditional duties of regimentation and
discipline. WOSEs are instrumental in implementing policies set out
by MINDEF, and are involved in areas such as manpower, logistics,
intelligence, training and operations. Today, many WOs are holding
appointments previously held by commissioned officers."
That was 2001. Since then, it's introduced a new career structure
& remuneration package under the the New Partnership scheme,
promoted a bunch of them to SWO's & - just recently - broke
ground to build the new SWI next to SAFTI MI (& which will
succeed the existing SISPEC & SAF Warrant Officers' School).
They're going to take the professionalism to another level; maybe
it'll teach staff-officer type courses for its own.
But, no, I don't believe there's any actual commissioning
"conversion" yet.
