it's not like you can do complex maneuver tactics when you rely on fast riders, bugles, drums and shouting to convey messages. war was figured out thousands of years ago, understand how an army would move based off it's state of supply and the territories they have to move in, with the equipment they need to carry, then how confident your men are, you understand basically everything on a high command level. the tactics boil down to either
>move left/right
or if you're hannibal
>keep the guys on the sides still while moving the center guys back slowly
you can only do more complex maneuvers with enough radios and then microsoft excel.
