Which battalion provides communications and information system support?

• A. MCISU
• B. Communications Battalion
• C. CI/HUMINT Company
• D. Civil Affairs Group

Answer: (B)

The main idea here is understanding which unit is built to run the network that keeps everything connected. A Communications Battalion is organized to establish, operate, and maintain the communications and information systems that let units talk to each other, share data, and stay linked to command and control across the battlefield. This includes planning and deploying voice and data networks, radio and satellite links, command-and-control information systems, and the cybersecurity measures that keep those systems reliable and secure under combat conditions.

That makes it the best fit because its entire mission is to provide that backbone of communications and information-system support for the force. The other options describe units with different primary roles: counterintelligence and human intelligence work, civil affairs operations with civilians and governance, or a unit focused on broader information systems support that isn’t the battalion-level communications backbone.
