How does the Avenger system communicate with other units?

The Avenger system communicates with other units primarily using secure radio frequencies. This method allows for real-time communication and coordination between different military units in the field. Radio frequencies are essential for maintaining operational security and ensuring that sensitive information remains confidential while allowing for effective command and control.

Secure radio communication enables the exchange of tactical information quickly and reliably, which is critical for the timely engagement of threats and coordination of defense efforts. The use of secure frequencies also minimizes the risk of interception by adversaries, enhancing the overall effectiveness of the Avenger system in a combat environment.

The other options, while they may offer alternative means of communication, do not align with the standard protocols utilized by modern military systems like the Avenger. Satellite links provide broader coverage but may introduce latency and are not as commonly used for direct unit-to-unit communication. Visual signals are limited by distance and visibility conditions, making them less reliable, while physical couriers are impractical in fast-paced military scenarios where immediate information is vital.
