Which CASREP type is used to introduce new or revised information about an incident?

• A. Initial
• B. Update
• C. Correct
• D. Cancel

Answer: (B)

In CASREP practice, updates are the message type used to bring in new information or revise what’s already been reported about an incident. After the initial report goes out with the first known facts, the situation often changes — more assets may be affected, statuses can improve or worsen, and estimated completion times can shift. An update communicates these changes so everyone has the latest, most accurate picture of the incident and its progress.

For contrast, the initial CASREP establishes the first known details of the event. A correction is used when an error is found in a previously sent report, and a cancel is sent when the incident is resolved or the report is no longer applicable.
