Captains are special units that significantly boost your military power in Battlecry.
Unlike regular commanders, captains enhance your strength by allowing additional units to be deployed in a specific category such as Army, Air Force, Navy, or Special.
The number of captains you can have depends on your level. You can have up to (your level × 3) captains for each unit category.
Using captains effectively can give you a major advantage in battles, especially against stronger opponents. They act as force multipliers and are essential for high-level gameplay.
