What are the five domains in the OE?

• A. Maritime, Land, Air, Cyberspace, Space
• B. Land, Air, Water, Space, Ocean
• C. Maritime, Land, Air, Space, Atmospheric
• D. Land, Water, Urban, Space, Information

Answer: (A)

Think about the environments where military operations occur across different theaters. The five domains are land, maritime, air, cyberspace, and space. The best choice lists the standard terms for all five: Maritime, Land, Air, Cyberspace, Space. It includes each domain and uses the recognized names for them. Other options fall short by replacing a domain with an unrelated term or by omitting a domain. For example, Water or Ocean isn’t the formal domain name, Atmospheric isn’t used as its own domain, and Urban or Information don’t represent the five OE domains.
