When I was in the military, our squadron commander thought all his leaders should be able to go 72 hours with no sleep on maneuvers other than the occasional 5 minute power nap in lulls. There were times when we were on the move for 36-48 hours. No-doz and straight Coke for that.

I once pulled a triple shift supervising a large asbestos abatement job. 24 straight hours without rest. The industrial hygienist on site finally ordered me to go home and said he would cover until the next supervisor came in. Then he promptly called the company I was working for and threatened to cite them for leaving the site without a supervisor. Got my ass chewed for that one.
