Explain the relationship between IO, IW, and cyber operations within military operations.

• A. IO encompasses all information-related capabilities; IW is a subset focused on maritime and national security.
• B. IW is the umbrella and IO is a subset.
• C. CNO is not part of IO.
• D. IO and IW are the same concept.

Answer: (A)

Information Operations covers the full range of information-related capabilities used to influence, disrupt, corrupt, or protect information and information systems across military operations. Information Warfare sits within that broader mission set and is the maritime and national-security-focused portion that brings together those information-related efforts at sea and in related contexts. Cyber operations are a fundamental part of Information Operations, integrated with other capabilities like electronic warfare, PSYOP, MILDEC, and OPSEC.

So, the best description is that Information Operations is the umbrella for all information-related capabilities, and Information Warfare is a subset focused on maritime and national-security applications. The idea that the umbrella would be Information Warfare, or that cyber operations aren’t part of IO, or that IO and IW are the same, doesn't fit how these terms are used in doctrine.
