absolutely - even though you physically do less as you rise up
your ranks, you shoulder more responsibility, meaning to say if
someone under your charge makes a mistake, you will have to bear
the brunt too even though it may be of no mistake on your part. a
DO is the highest ranking personnel in camp after office hours
(assuming all other officers have gone home). so you can imagine
how much responsibility he has to shoulder.
in any case, a DO still has to do quite a lot, including clearing
of ALL the armskotes, checking on the guards, going for staff
parades, and other odd jobs the FDO may task him, which may include
checking on various parts and persons in the camp (physically
sometimes) and sometimes the most unlikeable job of turning out
duty personnel, making him the most hatred person of all (when he
is simply doing his job...)
