May have to check out the GOM, anyway, to the best of my
knowledge, recruits are normally not given duties, but confinements
& fatigue.
Some BMTs actually let recruits have the experience of
performing guard duty (using only baton & shield ofcourse),
that is actually only performable from private onwards. The
experience is good, but recruits can have encounters with "evil"
spirits where many batches reported, then the recruit could have
permanent scarr on the encounter.
Guard duties is equivalent to COS. The basic job of COS is in
orderly activities, and much lesser especially after 7pm (after
dinner), there is only the standard switching on lights, ensure
armskote & CQ room is checked by BDO and cleared, people all go
off, or for dinner, lunch, etc, obtain BRO, update next day's
guards, ensure everyone bookin, flag lowering etc.
Guards - Pvt to LCP
G3 - CPL - 3SG
G2 - 3SG
GComdr - 3SG - 2SG
BSO - 2SG - 1SG
COS - PFC - LCP
Ok, most importantly is that 1st year units & 2nd year units
are different. In 2nd year units, most people doing G3 & COS
are normally LCP,CPL. But again, those that kena, is because they
kena extras, thus for 2nd year units, the LCP & CPL will kena
REAL extra duties, not confine in bunk and sleep all the way.
Everything varies camp by camp and nothing is fixed especially
when duty is concern cos each camp has different number of manpower
of each rank.
I was already a G2 when i was CPL and my G3 have been PTE or LCP
in the past.
