actually no lah. SIO [Senior Investigation Officer] is a
vocation, and not determined by rank actually. If you are a senior
officer, you will attain this qualification by the time your
first-ever posting [which will be in any Land Division's
Investigation Branch] ends. But this vocation is applicable to
junior officers too. So long as you have been sent for the course,
irrespective of your rank, you will be a qualified SIO.
Likewise for Team Leaders. The second posting for Senior
Officers, they will either be Inspectors or Assistant
Superintendents of Police [ASPs]. If junior officers are holding
this post, then the established rank will be Station Inspector [SI]
and above.
For commanders in Land Divisions, they will usually be
Superintendents [minimum]. Some will get their promotions while in
this post, so they will be Deputy Assistant Commisioners of Police
[DAC].
For Commanding Officers of the various NPCs, most are usually
DSPs, but there are the younger ones who might be holding this post
with a rank of ASP [usually scholars]. Operations Officers are
usually a minimum of ASP.
yup, people below that rank gets promoted to that post, and
likely that they will get promoted while in that post.
Like posting an ASP to NPC commander, most likely will get
promoted to DSP soon.
For SIO, it is the ranking officer of the day that will do
bah?
