What are the five main domains in multi-domain warfare?

• A. Air, Land, Maritime, Space, Cyberspace (information and electromagnetic spectrum)
• B. Air, Land, Ocean, Space, Cyberspace
• C. Air, Ground, Maritime, Space, Cyber
• D. Air, Land, Maritime, Space, Radiofrequency Spectrum

Answer: (A)

In multi-domain warfare, operations are planned and executed across five environments: air, land, maritime, space, and cyberspace. This arrangement reflects how modern forces project power, gather intelligence, and contest an opponent’s freedom of action in both physical spaces and the information realm. Cyberspace stands as its own domain because networks, data, and digital effects shape outcomes as directly as aircraft or ships do. The note that cyberspace involves the information and electromagnetic spectrum highlights how cyber actions depend on and interact with the broader spectrum of communications, sensors, and signals across all domains. Maritime is the standard term for sea-based operations, covering naval power and sea lines of communication; options using Ocean, Sea, Ground, or Radiofrequency Spectrum instead do not align with the commonly accepted five-domain framework.
