What does the acronym IFF stand for?

The acronym IFF stands for Identification, Friend, or Foe. This system is crucial in military operations, particularly in aviation and naval warfare, as it helps to identify whether an object in the air or at sea is a friendly unit, an enemy unit, or neutral. The primary purpose of IFF is to prevent friendly fire incidents, thereby ensuring safety among allied forces.

The correct terminology emphasizes the importance of clear identification in combat situations, allowing for informed decision-making when engaging with potential threats. An IFF system typically uses radar transponders and communication protocols to differentiate between friend and foe, enhancing situational awareness for pilots and commanders.

While other options may use similar terminology, they do not accurately describe the widely accepted and technically correct meaning of the IFF acronym as recognized in military jargon and operational standards.
