now, some tips on the fullpack 
1. for me i always keep a set of no. 4 in the fullpack in ziploc.
even now i ord liao, tt pack is still in my fullpack. oh dun forget
to include a pair of socks and some underwear together too.
2. i have at least 2 sets of mess tins: one for outfield use and
one for inspection. same applies to mess mug.
3. extra items to keep inside that will come in handy: extra
ziplocs (for keeping dirty clothes),
4. there will always be one pack with these items in my fullpack
too: (kiwi brush, boot lace, lighter, candles, extra gutters).
these are standard fullpack items but they may be in different
packs.
5. try to get those thick, translucent white trash bag (NOT those
black thin ones). put this inside the fullpack before dumping your
items inside (of course all the items will be in packs in ziplocs).
this is to waterproof all your stuff. if you are richer you can go
and get those bags that serve the same purpose (forgot wat its
called)
6. get the really small soapbox and toothpaste and toothbrush for
the pack that requires them. get a full roll of toilet paper and
remove its core too.
7. if u r required to put in ur PT shoes, well, last time i had 2
sets - one in the fullpack and one for use, so no need in the
morning of moving out den rush to squeeze the shoes in. but of
course, tt is abit luxurious, so no need to follow. anyway i used
the black rubberbands to tie the shoes together, squeeze them into
a big ziploc b4 putting them in.
8. eventually i could squeeze all the standard fullpack items into
the fullpack without using the side pockets at all, and still have
some space in the main compartment. this will be useful when u
receive like 3 days of ration which u have to carry together. and
eventually, my fullpack was always ready, such that, even if there
are outfield ex the next day, i dun have to worry about missing
items inside. can jus take and go! of course that comes with
experience and own preferences.
