Which term is NOT part of the DC organization's three-tier concept?

• A. RRT
• B. Cond II
• C. GQ
• D. SRT

Answer: (D)

The three-tier approach to damage control organizes response around three levels of readiness and action. The rapid-response element is the first line of defense, quickly moving to contain damage, isolate flooding, and secure critical systems. The second tier is Condition II, a formal readiness level that ensures compartments, equipment, and procedures are primed for rapid action—valves can be controlled, repairs coordinated, and damage control teams ready. The highest tier, General Quarters, places the ship in full battle readiness with DC teams manned at their stations and a shipwide posture geared toward managing major damage and preserving watertight integrity.

SRT does not belong to this three-tier framework. The established three tiers are represented by RRT, Cond II, and GQ, while SRT refers to a different type of team outside that structure, so it isn’t part of the DC organization’s three-tier concept.
