What is the Essential Element of Friendly Information (EEFI)?

• A. A critical element of a friendly operation that, if known by a threat would compromise, lead to failure, or limit success, and should be protected from enemy detection.
• B. A measure of enemy strength.
• C. A plan for logistics movement.
• D. A type of reconnaissance asset.

Answer: (A)

Essential Element of Friendly Information refers to information about friendly forces or operations that, if exposed to the enemy, could jeopardize the mission. The correct description captures that it is a critical element of a friendly operation whose disclosure would compromise, lead to failure, or limit success, and it must be protected from enemy detection. Think of it as the sensitive details that would give the adversary an edge if they learned them—things like exact movement times, routes, locations, vulnerabilities, or logistics plans. Keeping these elements guarded prevents the enemy from anticipating or disrupting the operation. The other options describe things that aren’t about sensitive bits of friendly information: measuring enemy strength refers to enemy intelligence; a plan for logistics movement is a planning task rather than a specific element that could be exposed; a type of reconnaissance asset is a resource or method, not information about what needs to be protected.
