Term used
in the Air Force, an
unknown aerial target, one that hasn't been identified as
friendly or hostile because of range, weather, or other reasons.
It is never a good idea to assume
the worst and engage bogies without IFF (Identify Friendly or Foe), you could end up shooting down a friendly.
Pilot 1: Bogies six o'clock!!
Pilot 2: Copy that! (Split S away)
Pilot 1: What's their ID? Over!
Pilot 2: Confirmed F-15 spike, they are
friendlies, over!
Pilot 1:
Roger that, return to formation!
