Deploy the army in a V shaped formation, just like a geese' flying formation. Keep the strike force in both tips of the wings. While engaged, the wings can break off and become a strike force on its own. If the enemy is too strong, the wings can flap and form a hook formation for defense.

Use this formation when you want to attack the enemy while you are weak in the center or while the enemy is launching a desperate attack to your center. This formation will turn your weakness into your strength. Try to lure the enemy to attack your center and to advance to the bottom edge of the V. The enemy will be weakened along the way by your archers and crushed from three directions when reaching the bottom. Use the divisions on the tips of the V to prevent the enemy from escaping or flanking your army.
