Azaroth observed his retainers as they attacked those checkpoints. He could sense the movements within those checkpoints.
The leader of each checkpoint had arrived near the entrance and was giving orders to his men. Under their command, they managed to contain the damage that would have further increased due to chaos in the military.
Azaroth had informed his retainers to kill this captain if they could.
Thus, this captain immediately had to move his body and dodge the incoming attacks. Soon, Azaroth's retainers were forced to block or dodge the attacks of the soldiers in this checkpoint.
Each one of his retainers observed their enemies carefully. They knew that they had to be careful when advancing for attacking these soldiers.
If he was surrounded here, it would be difficult to break through that encirclement.
They had already managed to get used to the encirclement tactics in the elemental training array designed by Azaroth.
