Was formerly an NCC cadet and am now a SISPEC trainee so I know
a thing or two about this arrangement.
The NCC runs on a kind of dual management track. Half of it is run
by the MOE and the other half by MINDEF since each ministry pays
for half of the operating expenditure of the Corps.
At the top of the management you have a Commandant who is usually a
Regular LTC who's arrived at the final 2-3 years of his career.
This final posting allows a senior officer to rub shoulders with
big shots from the two ministries without doing anything really
strenous.
At the middle level, you have the Teacher Officers, who were
seconded to the Corps by the MOE.
After that come the Warrant Officers. These are regulars who are
either rotated out after a 2-3 years or are posted there
permanently (usually due to medical downgrade).
Last come the NSFs. These are Officers and Specialists who were
lucky enough to be combat fit and Infantry-trained but hit the
jackpot when they arrived at the most relaxed posting possible for
someone with their background. Officers usually number around 5 and
specialists about double that number. Characteristics that are
usually seen for people posted to NCC are:
1) No tattoos
2) Usually from JC and speak decent English (for officers
especially)
3) Performed average in OCS or SISPEC. Not exactly the rotten worst
of the lot but never the best either. They don't send crap to NCC
since NCC tends to attract a sizeable number of whitehorses e.g.
Minister's sons, Senior officer's children...
