I was USAF. I was working with Air Rescue in an exercise - opposition was looking for us, heat, fire, smoke would have been an arrow pointing to us. So we were in a cold camp. No light, no fire. Eating rattlesnake was a challenge to those of us that weren't Air Rescue - we were playing shot down pilots and they wanted to see how far they could push us. Did so well, they kept inviting me back for other exercises.
Wow!
What is the longest you have been in a cold camp?
