to join the RSAF as a Senior Technician ( or your so called
junior engineer) is normally a vocation opened to regulars. Never
ever heard of NSFs, maybe as sai kang warriors to these Senior
Techs, but certainly not being a Snr Tech.
In any case, you would require a diploma in mech or electric or
aero engineering.
If you're from the A level route, do exceedingly well in your A
Levels and you can qualify to be an AEO. An Engineering Officer.
That is also an option, and i'm told most AEOs are very well paid,
and they rise through the ranks very quickly.
If you're an NSF, joining the infantry is not much a problem. It is
one of the biggest, if not the biggest, formations of the army. No
modern army undermines or belittles the use of the infantry.
From men to specs to Officers... many chances for you to be posted
to Infantry. Just ask your PC/PS when you're in BMT. be warned...
being in the infantry is not as glam or 'cool' as you think.
Imagine digging for 2 days and when you're done...it rains and your
sleeping area becomes a nice 'water bed'. Many more horror stories
awaits...haha...
Colour blind people, in severe cases, cannot join combat vocations.
Although I know of a colour blind friend who became an
Officer.
