POSID is essential to prevent fratricide because it verifies what?

• A. Confirming that the target is a legitimate enemy or target.
• B. Confirming friendly positions.
• C. Confirming weather conditions.
• D. Confirming aircraft altitude.

Answer: (A)

POSID, or Positive Identification, is the process of confirming the target’s identity before engaging. The essential point is to verify that the target is indeed an enemy or the intended objective, not a friendly, civilian, or noncombatant. This direct confirmation helps prevent fratricide by ensuring you don’t strike a unit that’s on your side or not a legitimate target.

In practice, you rely on multiple cues and corroboration—visual markers, unit signatures, IFF/interrogation data, call signs, and coordination with ground observers or other sensors. If you can’t positively identify the target, you don’t engage and you seek further confirmation or a safer engagement alternative. The other options—confirming weather conditions, aircraft altitude, or confirming friendly positions—don’t address target identity and thus aren’t the primary purpose of POSID.
