🔍 Key Concepts

• Understand what Naval Control of Shipping (NCS) is intended to do during wartime or heightened threat conditions • Know which authority has operational control for directing merchant ship movements, including routing and diverting • Distinguish between national policy/administrative roles and tactical/operational control roles in maritime defense

💭 Think About

• Ask yourself: Which of these choices actually gives direct orders to ships and convoys about where and when to sail under NCS? • Which option sounds like a policy or support organization, and which sounds like the one that would make real‑time routing and diversion decisions in response to threats? • In wartime, who would most likely coordinate convoy routes, diversions around danger areas, and timing in conjunction with naval operations?

✅ Before You Answer

• Check which role is typically described as having operational control rather than just administrative or advisory authority • Verify which entity is formally linked to Naval Control of Shipping doctrine for routing and diverting ships • Make sure the choice you pick could realistically change a convoy’s route on short notice in response to enemy or threat information
