In SISPEC .. it is very common for ADF men to teach the
instructors!!! haha.
ADF men usually in force for 3-4 years already and its 3-4 years of
outfield and training. SISPEC instructors are just fresh pass
outs.
For me, i had to explain to my CSM and PC why SAF uses mils rather
than degrees.
and how "mils" is derived from.
From then on, they never dared to disturb me on anything to do with
topo and navigation.
