What are the different troop formation?

Troop formations are strategic arrangements of military units that enhance effectiveness during combat. Common types include the line formation, which maximizes firepower; the column formation, ideal for movement and maneuverability; and the square formation, historically used to defend against cavalry charges. Other formations include the wedge, which focuses on breaking through enemy lines, and the skirmish line, employed for flexibility and to engage the enemy while minimizing exposure. Each formation serves specific tactical purposes based on the battlefield scenario.
