What Is DA Form 3120?

DA Form 3120 is the official U.S. Army form titled Missile Firing Data Report (PATRIOT) (previously covering HAWK, NIKE, and PATRIOT systems). Units use it to record detailed technical and operational data for every missile firing attempt.

The form falls under DA PAM 700-19 (Procedures for the U.S. Army Munitions Reporting System) and carries Report Control Symbol AMC-224. It is marked CONFIDENTIAL when filled in due to sensitive performance and tactical data.

Purpose of the Missile Firing Data Report (PATRIOT)

Army units complete DA Form 3120 for every PATRIOT missile firing (live or practice) to:

  • Capture detailed firing conditions, missile performance, target data, and engagement outcomes.
  • Support stockpile reliability programs and shelf-life determinations.
  • Identify trends in malfunctions or unsuccessful firings for corrective action.
  • Provide data to the U.S. Army Aviation and Missile Command (AMCOM) at Redstone Arsenal for analysis.
  • Ensure compliance with munitions reporting and range safety requirements (see DA PAM 385-63).

Accurate reporting helps maintain the readiness and effectiveness of the PATRIOT system, a cornerstone of U.S. Army air and missile defense.

When to Use DA Form 3120

Complete the form for:

  • Service practice firings.
  • Tactical or training missile shoots (single or salvo).
  • Any firing attempt, successful or unsuccessful.
  • Events at ranges or during exercises involving PATRIOT missiles.

Submit copies to the installation Ammunition Supply Point (ASP), Brigade Ammunition Officer (BAO), and AMCOM as required by local policy and DA PAM 700-19.
