I remember that for outfield, I would only bring the dog
biscuits. I would also buy one whole box of Uncle Toby's bars.
All that would last me for three days. After all, during
planning for deliberate attack, we would get fresh rations anyway.
During the rest of the time, there was hardly any time to eat
anything proper.
Needless to say, I lost an average of 3 kilos during an average
three-day outfield mission. 
usually, we'd gain a shitload of weight on an outfield mission
coz we'd sit around, do nothing except inhale whatever the hell we
brought with us, whatever Tuas Seafood (at that time) sold and
basically smoked way too much..
the guys would smoke a carton of cigarettes in 5 days then come
badger me for cigarettes for the remaining 2 during a 7 day
exercise..
then we'd go to Tuas Seafood to stock up on "Vitamin
T"
