The Roman Legion of the Republic

The romans took great care in insuring they held the high ground and were in a well defensible spot. A routed roman army often staved off final defeat behind the walls of their camps. And many roman victories were secured by overrunning the poorly constructed camps of their enemies. The fight itself became almost an afterthought. It was the boring details of making sure everyone had proper footwear and that the trenches were dug to a proper depth that really set the romans apart from their enemies, who often had every intention of just showing up for a fight.
