The people who do the special taks -not military- AFAIK, have college degrees. The plush jobs need connections/pedigree -sons of officials. Tasks range but yes, include taking care of the elderly, paper delivering, computer fixing, hosts in museums and basically, everything else they can think of so gummit does not have to spend money.
I know a pal was teated with care because he was an Overseas Taiwanese, married with children, and ended up in the Army.His superiors would prevent him from performing certain tasks, saying it was too dangerous. So it stands to logic that there would be previsions for special cases.
It is important though to read the fine print. There are certain rights that serving provides, and it seems if you do the specil stuff you do not get the full reward. Do ask throughly.
