Describe a scenario where 'joint fires' across domains are required.

• A. A ground unit conducts a standalone maneuver.
• B. A cyber-only operation.
• C. A space-based weather operation.
• D. An adversary shields a high-value target with air defenses; cross-domain fires coordinate long-range missiles from land, air-delivered munitions, and cyber/space effects to suppress or destroy threats.

Answer: (D)

Cross-domain fires are needed when a high-value target is protected by integrated defenses that rely on sensors, missiles, and command-and-control links spread across land, air, space, and cyberspace. In this scenario, the adversary atmospherically defends the target with air defenses, so success depends on a synchronized mix of effects from multiple domains. Long-range missiles from land allow you to reach and influence the threat systems without exposing your forces to their reach. Air-delivered munitions provide flexibility and speed to engage defenses that remain responsive at different ranges. Simultaneously, cyber and space effects can degrade radar, communications, and ISR networks, eroding the enemy’s ability to detect, decide, and respond. The combination creates a window of opportunity to suppress or destroy the threats and then attack the high-value target, something a single-domain action cannot achieve.

A ground maneuver by itself lacks the cross-domain integration necessary to defeat layered air defenses. A cyber-only operation does not produce the physical fires needed to suppress or destroy the protective systems. A space-based weather operation, while valuable, does not involve offensive fires aimed at neutralizing the defenses guarding the target.
