The Announcement group broadcasts to which groups?

The Announcement group broadcasts to which groups?

• A. The assigned talk group only
• B. External agencies only
• C. The assigned talk group and expansion groups
• D. Internal city channels only

Answer: (C)

The Announcement group is used to reach both the assigned talk group and any expansion groups that are active for the incident. The assigned talk group is the primary set of units working together, while expansion groups add additional units or agencies as the response scales up. Broadcasting to both ensures every key unit hears the message, from the core team to the extended teams. It’s not limited to external agencies or only internal city channels—the system targets the primary group plus the expansion groups so everyone involved gets critical instructions.
