The tactical communications system should include a network backbone with connectivity, a switching and routing layer, and user management. The network backbone should include fiber-optic, microwave, and satellite transmission links. The switching and routing layer should provide data packet routing between nodes on the network, as well as access control and authentication. The user management layer should enable the authentication of users to ensure secure access to the network and its services. This layer should also manage user accounts, including authorization levels and access rights to resources. Finally, the system should include a radio transceiver for voice communication.
