The sonar

The Sonar Operator is the submarine’s eyes and ears in the treacherous darkness of the Abyss. He can scan the environment for threats, mark points of interest, and set waypoints. During the battle, the Sonar Operator can reveal the weaknesses and track the movement of hostiles, providing life-saving information to the Gunner.
