What are the five MDO domains?

• A. Land, Air, Maritime, Space, and Cyber
• B. Land, Air, Space, Cyber, and Ground
• C. Land, Sea, Air, Space, and Information
• D. Terrain, Air, Maritime, Space, and Cyber

Answer: (A)

Multi-domain operations train to produce synchronized effects across all the main operating environments. The five domains are land, air, maritime, space, and cyberspace. Each domain represents a distinct arena with its own assets, methods, and challenges: land covers ground forces and terrain; air encompasses aircraft and aerial maneuver; maritime includes naval and littoral operations at sea; space enables satellites and space-based capabilities for surveillance, communication, and navigation; cyberspace involves networks and digital infrastructure, where cyber operations shape information and connectivity. The reason this set is the best is that it matches the standard five-domain framework used to integrate operations across all environments, with maritime reflecting naval and coastal activity and cyberspace handling the digital layer. Alternatives swap or add domains (like sea instead of maritime or information or terrain) that don’t align with the established five-domain model.
