I guess it really depends what "sensitive" is.
As far as I know, the 2nd Gen PRs i served with so far hasn't
been to sensitive command. The most "sensitive" 2nd PR i know is Dy
S2 of a battalion, he only in singapore less than 6 months before
NS.
I am one myself, but i wasn't cleared to be Armskote spec. For
some reasons i don't understand till today even though I have been
in Singapore for 20+ years.
Other 2nd Gen PRs i know, Arty PC, SAR PC, etc etc.
And if my memory don't fail me, I think our first CON was a
taiwanese.
