Yeah, for most people 72 hours is the limit. I think 10 days is the world record. LTC Grossman did some good work on sleep deprevation. There's short duration where a person stays awake for 3 days and then there's long duration with limited sleep over time. Back in the day 4 hours was considered the minimum for being able to maintain good function over long periods. I know from experience I can do 4 hours sleep under high stress and high activity for about 2 weeks, then I need to crash for 6-8 hours of solid sack time. It's just how my body works. In my experience most troops do pretty well over long durations with 6 hours sleep. LTC Grossman's work found that for sustained top notch performance 8 hours a night was optimum. But in the military during on going operations, no one is getting that.GrumpyCatFace wrote:I did 72 hours on my feet, holding my hand on a car for super bowl tickets.

After a few days, you totally understand why they use sleep deprivation as torture. I wouldn't bother with waterboarding, sleep dep will break anybody in the end, it's just a matter of time.
Sapper school is a tough one because in the middle to late part of the course afte 2-3 weeks of little sleep you have to complex calculations for explosive charges and bridge weight capacities. It's not that the work is so hard to do, but doing those calcs after a total of 30-36 hours of sleep in 3 weeks is what kills you.
