there is a great deal of lifting, grunting, and swearing. this is broken up by wind sprints across the field to escape attack. there is a constant buzzing in the ears which you do your best to ignore. stealth and cunning are employed to deny the opponent it's territory and to take supplies from same. the reward at the end of the day is a good meal eaten with the fingers sitting in the grass. all that's missing is the M16, and the smoker is the substitute for that weapon.
