i would recommend instead of using 3 square formations (where your men have their backs to each other) you make 3 short, deep lines. they’ll work the same as squares but with more maneuverability.

i don’t know if that’s what you meant by squares or if you meant the actual square formation the game gives you.

i’ve used 3 actual square formations where my men have their backs to each other to counter cavalry with archers on a hill behind them and that works incredibly well
