When I was in high school I participated in our school army cadet course and one of our tasks was to be dropped off in the middle of nowhere in the bush, find a target and navigate our way back to a set camp. It was done over 4 days and we had to survive on what we were rationed at base camp. I guess the terrain is very different to what you would have in the States Ed, dry eucalyptus, steep hills, etc typical Australian terrain, but it was quite challenging all the same (not to the extent of your training obviously!). Of all the platoons, all of them got lost except for one - thanks to the fantastic navigational skills of their navigation officer

I thought it was quite good for a 15 year old

Thats the extent of my 'army' experience - tough but quite exhilarating at the same time
