“War” games are fundamentally different from “battle” games, although most people would call both wargames. In the former there’s an economy and the war is essentially about controlling a better economy that ultimately gives you the preponderance of force. The focus tends to be strategic rather than tactical with maneuver contributing to gaining or keeping control of economic locations.
In a battle game you have an order of appearance that rarely changes, and no economy. Then the focus tends to become tactical, finding better ways to butcher the enemy before they butcher you. There may be objectives that are locations on a map, but if you slaughter enough of the enemy you’re likely to take those objectives. Maneuver then contributes to killing the enemy (or scaring them off) not to capturing/controlling economic resource/production locations.
