COMDTINST 5400.7D is the Coast Guard manual for what?

• A. Coast Guard Organization Manual
• B. Tempest Policy and Countermeasures manual
• C. Freedom of Information and Privacy Acts manual
• D. Crypto Repair Facility operations manual

Answer: (A)

Understanding how Coast Guard directives are organized helps you see why this one matters. The number and series of a COMDTINST indicate its subject area. The 5400-series instructions generally cover internal management and how the organization is structured and operated, with the suffix showing the revision level. COMDTINST 5400.7D is the Coast Guard Organization Manual, the reference that lays out the command structure, chain of command, and responsibilities across the service. It provides the framework for how units relate to one another and how authority flows.

Other topics like tempest policy and countermeasures, the handling of Freedom of Information and Privacy Acts, or Crypto Repair Facility operations belong to different manuals with different numbers and titles, so they aren’t what this specific instruction covers.
