change your UNDERWEAR and SOCKS every night. don't care if you
don't want to change your long 4s or whatever, but these areas are
important so change to dry ones at night when they ask you to
powder bath. remember to POWDER THEM too. well don't worry they'll
ask you to powder yourself with prickly heat so its ok. but
remember these two are important. (don't over powder ok cause i did
it once and i almost died from 'freezing'
) trust me, foot
rot and crotch rot is NOT nice.. 
drink lots of water while on march.
during a company file formation, try not to get the laaaaast man
(but no choice in this cause it's usually plt 1, 2, 3 & 4 and
in that their individual sections) cause you'd have to kneel while
waiting for your turn and that sucks. i was the company's last
platoon, last section, last bed.
at reclaimed land campsite(the one near SIT test site), you better
make sure you put alot of insect repellent (put on your 4s not on
skin cause it's been known to burn.) put at the collars, button
areas, sleeves, SBO even. don't be like me, put on my cuffs (the
wrist area of my 4s) then next morning forgot i put it there, wipe
my whole face with it (cause that's what you do when you want to
remove/apply camo) then the next thing i knew, my forehead and eyes
were burning. nice. don't think other camp sites have that bad a
case of the mozzies but reclaimed land's got SOF mozzies i tell
you. they bite EVERYWHERE. from legs to hands to face to groin. so
enjoy. 
if you want to throw your rations to lighten your load, don't get
caught. period.
load your SBO with biscuits from the accessory pack (your
commanders will tell you to do this anyway) so that you can eat
during lessons. i tell you you'll be shagged so people will tend to
sleep, so to play it safe load the biscuits. Standard Biscuit Order
/ Full Biscuit Order.
your movements better be FAST. try not to give sloppy movement,
else "whole lot knock it down!"
try to smuggle in a snickers bar. don't get caught. period.
disposal is by black tape. (i did NOT say this ok.)
sprinkle prickly heat around your basha to minimise the possibility
of a centipede coming in. during my camp, 2 of my friends kena on
the same night. one had 2 bites, the other had one big one on the
arm.
don't need to take out the black attachment and washer cause the
commanders won't take that anymore. it's not a tactical 'advantage'
or however you put it, you know what i mean? hell, if you take it
out chances are that you are more likely to lose it. mags, dunno
about the rest but i put mine in my side pockets. rifle, just sling
around body and hug. if you're paranoid, unbutton your 4, put your
rifle in between, button over.
go to beach road, get the glow-tapes. put small tapes on everything
of yours that's loose. eg, helmet, bottles, powder bottle, rifle
maybe, sbo, ET kit..etc.. this will help you find you stuff at
night. well, it helped me.
if you want to make life easier, get an extra tent pin so it'll be
easier for you to remove the pins which are already stuck in the
ground. if you want to leave it outside, you can get one of those
silent straws that are lying around and tie it to the extra
pin.
just enjoy fieldcamp lah. remember this one won't be as bad as the
ones you'll get in command school (or so they say). look at how
fast time flies and soon you'll know it's over. the end of field
camp (the trip back to coy line) isn't the end yet. you still have
to clean your stores etc. it'll be damn hectic i tell you. have
fun.
edit: omg didn't know i could ramble so much..
carry on carry
on..
