[concept created by Unexpected]
The Polish-Lithuanian hussars' primary battle tactic was the charge. They carried the charge to, and through the enemy. The charge was slow at first and carried in a relatively loose formation. The formation gradually gathered pace and closed ranks while approaching the enemy and reached the highest pace and closest formation right before the attack. They also tended to repeat the charge several times until the enemy formation broke (they had supply wagons with spare lances). The charging attack, and heavy weight of their armour and horses guaranteed victory for nearly two centuries.
