Final answer:
It is false that upon Declaration of INFOCON upgrade an OPREP-3 stating the reason for the change will not be necessary; such a report is, in fact, required to document the event and inform commanders and national authorities.
Step-by-step explanation:
True or False: Upon Declaration of INFOCON upgrade by the Installation Commander, an OPREP-3 stating the reason for the change was directed will not be necessary.
False. When an Information Operations Condition (INFOCON) level is upgraded, it signifies a heightened state of alert due to an increase in the threat to a computer network. The purpose of changing the INFOCON level is to help protect operations against cyberattacks and other threats. In the event of an INFOCON upgrade, not only must relevant defensive measures be initiated, but also according to protocol, an Operational Report-3 (OPREP-3) needs to be completed. This report is required to document significant incidents or changes in military readiness; it provides essential information to high-level commanders and national authorities, including the reason for the INFOCON change.
