Examples of use of Identification Friend or Foe
1. The inquest heard all jets were fitted with an Identification Friend or Foe (IFF) device which emitted signals to radars on the ground to confirm they were part of the coalition forces.
2. Defense Minister Sergei Ivanov insisted that the loss of the device, known as "identification friend or foe," or IFF, was not a security threat because it had most likely self–destructed its sensitive information.
3. "I saw nothing more and carried on and landed." He told the coroner that the coalition had systems in place to prevent such attacks, including an Identification Friend or Foe (IFF) system that emits an encoded signal when spotted by radars on the ground to confirm that it is not a threat.
