Discovered this a few days ago. Spearmen can charge 3 strait, or 2 bank. Which is faster?
Initially I though 3 strait, right?
Wrong.
A 2 wide tray ends a 2 bank charge with it's outside corner just a bit further than a 3 strait move.
A 3 wide tray ends a 2 bank charge with it's outside corner move than range 5 forward of it's starting location, roughly dead ahead of the center of it's starting spot.
In theory, you could metered march to end just outside of range 5 of an enemy, and on the following turn, order a 2 bank charge and swing your outside corner into contact; covering the firing range of the enemy without them getting a shot off.
Try playing around with straits and banks and see where the units end.
