That may be true. I got out in mid '05. Things could have changed, but we sure worked our asses off.
Even when we weren't working on gear, we still had to build out own barracks (out of a bombed out office building) including getting water and electricity, guard TCNs, set up our own security, and all the other misc jobs that come with deployments. Hell, just making sure the roads were clear of unexploded ordnance took weeks.
Mostly what we would do is run two shifts of 12 hours each, then everyone would spend 2 to 4 hours after their shift doing whatever needed doing. That doesn't mean we didn't get any downtime, just that it was literally when we couldn't find anything to do. We got a few days off too. Couldn't schedule them, but if there was nothing to do we'd try to rotate out one or two guys.
