I find the Roman military camps to be fascinating things. They constructed them each evening while on the march, and completely dismantled them when they got moving again. Each man carried a piece of the palisade. It seems like a huge endeavor, but they accomplished it daily.

My question is, were the Romans unique in this? I realize that all armies created encampments, but did any other ancient civilization make encampments on the scale of the Romans? Polybios writes of them as if they were remarkable for their time (however, that my be my own interpretation).

If you want detailed information about the encampments, I recommend Hannibal by Theodore Dodge.
