Battalion

Battalions are a new feature introduced in Fire Emblem: Three Houses.

Overview
Battalions take the form of squads of units that can be deployed alongside characters and will assist them in battle. Different Battalions can be equipped to a character depending on their rank of Authority. As a character ranks up their authority, they can equip different battalions and learn different gambits. As a character takes damage, the battalions health will decrease. Once a battalion's health reaches zero, effects from the battalion will disappear and Gambits cannot be used.
