DA Form 4379-SG: Ammunition Malfunction Report Guide

DA Form 4379-SG: Ammunition Malfunction Report Guide – The DA Form 4379-SG is the system-generated version of the Ammunition Malfunction Report, a critical document used by the U.S. Army to report malfunctions involving ammunition and explosives. This form helps ensure safety, support investigations, and maintain stockpile reliability across Army units.

Accurate and timely reporting via DA Form 4379-SG protects soldiers, prevents future incidents, and enables the Joint Munitions Command (JMC) to analyze trends and issue suspensions or restrictions when necessary.

What Is DA Form 4379-SG?

DA Form 4379-SG is the current system-generated (SG) electronic version of the Ammunition Malfunction Report, prescribed for use under AR 75-1, Malfunctions Involving Ammunition and Explosives. It replaced or updated earlier versions (such as DA Form 4379 and 4379-R) and was updated around June 2023.

Unlike traditional fillable PDFs, SG forms like 4379-SG are generated and submitted through authorized Army systems, primarily the Munitions History Program (MHP). A companion form, DA Form 4379-1-SG, handles missile and rocket malfunctions.

Key Purpose:

  • Document malfunctions (including duds, misfires, and other defects).
  • Initiate investigations.
  • Support safety actions like lot suspensions.
  • Provide data for quality assurance and reliability programs.

Why Proper Reporting Matters for US Army Units?

Ammunition malfunctions can range from minor (e.g., failure to fire) to serious (Class A/B incidents involving injury or damage). Reporting via DA Form 4379-SG:

  • Ensures compliance with AR 75-1.
  • Helps identify manufacturing or storage issues.
  • Protects personnel by enabling rapid response and restrictions.
  • Contributes to the overall safety and readiness of Army ammunition stockpiles.

Failure to report promptly can delay critical safety notifications and expose units to unnecessary risk.

When to Use DA Form 4379-SG?

Use this form for all malfunctions involving conventional ammunition and explosives (Class V items), excluding guided missiles and large rockets (which use the 4379-1 series). This includes:

  • Duds and misfires.
  • Premature detonations or other explosive malfunctions.
  • Any incident where ammunition does not perform as expected.

Preliminary reports should be made as quickly as possible (often by phone or immediate notification to JMC), followed by the detailed DA Form 4379-SG submission.

How to Submit DA Form 4379-SG (Preferred Method)?

The preferred method is through the Munitions History Program (MHP) at https://mhp.redstone.army.mil (CAC required).

Steps:

  1. Access MHP with your CAC.
  2. Navigate to the malfunction reporting module.
  3. Complete the system-generated fields for DA Form 4379-SG.
  4. Submit electronically to JMC.
  5. Provide information copies to your local safety office and command channels as required.

If MHP is unavailable, use a hard copy of the legacy DA Form 4379 (available on Army Publishing Directorate) and mail, scan, or email it to JMC. Always follow AR 75-1 for classification and secure transmission if needed.
