operational missions in the field.
3
, What is the function of the Automatic Link Establishment (ALE) system in military
communication?
✔✔To automate the process of establishing and maintaining secure communication links over
radio frequencies.
What is the role of the Air Force's Command and Control (C2) systems?
✔✔To facilitate the management and coordination of Air Force operations, ensuring effective
decision-making and resource allocation.
What is the purpose of an antenna in a communication system?
✔✔To transmit or receive electromagnetic waves, allowing for the transfer of information
between devices.
How does the Air Force utilize fiber optic cables in communication systems?
✔✔For high-speed, high-capacity data transmission over long distances, providing secure and
reliable communication links.
