Which of the following rates is focused on both firefighting and structural repair?

The Damage Controlman is the rate that is focused on both firefighting and structural repair within the Coast Guard. Damage Controlmen are trained to prevent and manage damage during emergencies, which includes fighting fires on board vessels and conducting repairs to the ship’s structure, including watertight integrity. Their expertise ensures that they can effectively respond to incidents that compromise the vessel's safety and security, maintaining operational readiness and the safety of all personnel.

In contrast, the other rates listed do not encompass firefighting and structural repair responsibilities. Electronics Technicians specialize in maintaining and repairing electronic systems, Divers focus on underwater operations, often related to inspections and repairs, and Information Systems Technicians manage information technology systems and data networks. Therefore, their training and responsibilities are distinctly different from those of a Damage Controlman, who must combine firefighting skills with structural repair techniques.
