What are Essential Elements of Friendly Information (EEFI)?

Essential Elements of Friendly Information (EEFI) refer specifically to critical information that, if disclosed to adversaries, could jeopardize friendly operations or compromise the safety and effectiveness of military forces. This encompasses sensitive data that may include troop movements, operational plans, and intentions that may be targeted by the enemy.

Recognizing EEFI is key in maintaining operational security (OPSEC) since it helps military personnel identify and safeguard the most sensitive aspects of their operations. By doing so, the military can prevent the enemy from gaining insights that could lead to tactical advantages over friendly forces, ultimately enhancing the chances of mission success.

The other options, while related to military information and strategy, do not capture the specific definition or implications of EEFI in the context of operational security and the safeguarding of military operations.
