Which choice best illustrates a cross-domain fire in Multi-Domain Operations?

• A. Cyber operations degrading sensors to enable artillery fires.
• B. Using field artillery to destroy an enemy base in the same domain.
• C. Naval gunfire against a land target.
• D. Air defense intercepting an aircraft.

Answer: (A)

Cross-domain fire is about using effects in one domain to enable or amplify fires in another. Here, cyber operations degrade the enemy’s sensors, which undermines their ability to observe, locate, and react. That directly creates a more favorable, lower-risk situation for land-based artillery to strike, demonstrating a clear cross-domain linkage: cyber effects shaping fires in the land domain. The other scenarios don’t show that cross-domain enabling effect. A field artillery strike within the same domain isn’t cross-domain. Using naval gunfire against a land target starts a cross-domain action, but it doesn’t illustrate the cyber-to-kinetic enabling sequence. An air-defense intercept is within the air domain and doesn’t involve cross-domain fire.
