For those who got posted to Sig Ops, below's a mini "FAQ"
credited to dvcx 
1) What exactly is a Sig Ops and how does it differs from a
Signaller?
2) The duration of a Sig Ops course and if there would be a
confinement period?
3) What to expect of the course and my time in Stagmont
infocomm2?
4) What kinda unit would I be posted to after course?
5) Is there really a need to bring in all those SAF-issued
items?
--------------------------------------------------------------------------------
1) He say he doesn't know that there is a difference between the
2.
2) There is unlikely to be a confinement period, weekend go home
one, unless you get guard duty. the duration is about 7 weeks to 11
weeks, depending on the course you go into
3) Inforcomm2... i think it is about 7 weeks? i can't confirm it,
the course is physically more intensive than IC1 or IS. You tend to
carry signal sets and run around (hes surprised C9L9 get posted
there and say you might OOC )
4) Unit to post to is a lot a lot lor, but chance is high is 3SIG,
2SIG and 6SIR
5) Yes, it is required, although if you didn't bring on the first
week, it is reasonable to assume the commander would let you off.
So long as you don't be too much
I just copy and pasted this from a post almost 2 yrs ago. had to
dig through all the pages to find it. lol. so, for pple who get the
same vocation as me (SIG INSTITUTE, INFOCOMM2) here are some
info.
btw, im pes C as well. but my fren from pes A got the same
posting.. when i see it stated that it is quite physically
intensive, i wonder why diff pes get same vocation sia. i mean i
dont mind xiong but im worried that my current injury will get
worse..hope they teach me how to train with my injury then.
hmmm and why highest rank can only get CFC sia? izzit cos the
vocation is not considered a specialist (hence cant get spec rank).
i mean, 3SG and CPL the pay quite big difference :S but then again,
if all vocation can get 3SG then no point liao. haha
