Definitely combat side; life is more meaningful there. *shrug*
Might as well do something more tangible when in NS.
If cannot tahan the sweating part with the combat arms units, then
can always aim for combat support (medic, comms, provost, etc.) or
combat service support (supply, maintenance, transport,
etc.).
Admin life deals too much with paperwork, office politics & the
military bureaucracy IMO.
