Changes to the EMCON state will always be sent by what?

• A. Secure means
• B. Public broadcast
• C. Unencrypted email
• D. Plain radio

Answer: (A)

EMCON state changes are critical, time-sensitive commands that directly affect how detectable you are and how you operate. Because these instructions can reveal your location, readiness, or alter mission security, they must be protected against interception and tampering. Transmitting them over secure means ensures confidentiality, authenticity, and integrity so only authorized units receive and can act on the change. Public broadcast, plain radio, or unencrypted email would expose the instruction to anyone listening or capable of spoofing it, making them unsuitable for this purpose. Using secure means keeps the command legitimate, protected, and effective.
