Just like any army, I suppose. It does not count the time wasted
during exercises, where we were told to move quickly to an
objective and then wait for half day or more, for some other unit
to catch up or finish its planning activities.
But then real war will be like this too. And most people took the
time to mix and chat with friends. That's how camaraderie is built
up too. Not just in the field but during such boring hours.
