For the no. 1 uniforms, a concern member of the public did write
in to the Straits Times Forum pages last year or a few years ago,
saying that its only the SAF and SPF who wears no. 1 year in year
out for NDP as part of the Guard of hounor contingent, however, the
writer hopes that SCDF can also be part of the said contingent
rather than just a supporting contingent, which includes the SAF
and SPF and uniform groups.
I would like to point out that it is not easy to get no. 1, as you
would notice that the SAF and SPF contingent commanders carry
swords, which is "against" {note the inverted commas} the SCDF's
mission of " to protect and save lives and property for a safe and
secure Singapore" (credit: http://www.scdf.gov.sg/General/About_Us/corporate_philosophy.html).
Moveover, the only most relevant thing next to the sword would be
the axe.
For NCDCC, since SCDF is its parent organisation, it will have to
follow suit.
May be good to ask LCP Cai, since he is posted to you know which
branch in HQ.
