Which statement best describes Essential Elements of Friendly Information (EEFI)?

• A. It refers to sensitive information that, if disclosed, could reveal friendly intentions or capabilities.
• B. It is a weather indicator.
• C. It is a type of encryption protocol.
• D. It is a unit's supply status report

Answer: (A)

Essential Elements of Friendly Information are pieces of information that, if released, could reveal friendly intentions or capabilities to an adversary. This directly matches the statement describing sensitive information whose disclosure could reveal what friendly forces intend or can do. Planners protect these elements to prevent revealing movement, timing, capabilities, or plans. The other ideas refer to unrelated concepts: a weather indicator isn’t about operational security; an encryption protocol is a protective method, not a type of information to be safeguarded; a unit’s supply status report is logistics data and not inherently about exposing intent or capability.
