We were typically awake for about 48-72 hours straight during field training exercises in a combat unit. Somewhere between 36 and 48 hours you start micro-napping, even in the middle of performing other tasks. I remember falling asleep while walking between buildings multiple times. I'm not sure what goes on today, I separated nearly 20 years ago, but back in the early 00s we were doing these FTXs at least twice a year between deployments.
