What must be sent before ASCA messages can be exchanged?

• A. Full Unit Briefs
• B. Encryption Keys
• C. Basic Unit Status Reports
• D. Access Credentials

Answer: (C)

Establishing mutual awareness and trust is essential before sending operational messages. Basic Unit Status Reports provide the initial snapshot of who is on the network, where the unit is, and what its current capability and readiness are. By sharing identifiers, location or area of operation, current task, readiness level, and available communications assets, each side can verify the other's presence and legitimacy, route messages correctly, and decide whether to proceed with more sensitive ASCA communications. Full Unit Briefs would be more detailed than needed at this early stage. Encryption Keys are important for secure messaging, but key exchange happens through separate security processes rather than serving as the gating step for starting ASCA communications. Access Credentials matter for authentication, but the immediate prerequisite described here is having a Basic Unit Status Report to establish the baseline and trust before exchanging ASCA messages.
