That really really depends on how well you prepare.

  Well but if you look at it from another angle, you can simplify your logistics if you can train soldiers to not need regular sleep breaks - and that is of value during war. If one is to believe Suvorov, the Soviets designed their logistics so that they didn't have to ship food and sleep bags to the front lines - soldiers were expected to fight three days without food or sleep, and then retreat to have few days of break with as much food and sleep as they wanted, while the next wave of well-fed and fully rested soldiers was sent in their place.
