DA Form 2011-1: COMSEC Equipment Register (Using Unit)

DA Form 2011-1: COMSEC Equipment Register (Using Unit) – U.S. Army units and personnel responsible for managing Communications Security (COMSEC) equipment rely on proper accountability tools. DA Form 2011-1 serves as a critical record for tracking COMSEC equipment at the using unit level.

What Is DA Form 2011-1?

DA Form 2011-1, titled COMSEC Equipment Items Register (Using Unit), is an official U.S. Army form used to maintain detailed accountability records for COMSEC equipment items issued to or held by using units.

It complements DA Form 2011 (COMSEC Aids Items Register) but focuses specifically on equipment rather than keying material or aids. The form is prescribed by TB 380-41 (Procedures for Safeguarding, Accounting, and Supply Control of COMSEC Material) and falls under the broader COMSEC Material Control System (CMCS).

Note: The March 2006 version (DA FORM 2011-1, MAR 2006) remains the referenced standard, replacing the obsolete November 1977 edition.

Purpose of the COMSEC Equipment Items Register

The primary purpose of DA Form 2011-1 is to provide a standardized, auditable record of COMSEC equipment under a using unit’s control. This ensures:

  • Accurate tracking of serial-numbered or quantity-accountable items.
  • Proper documentation of receipts, transfers, loans, and on-hand balances.
  • Compliance with Army COMSEC accountability and inventory requirements.
  • Support for semi-annual inventories, change-of-custodian inventories, and audits.

COMSEC equipment includes cryptographic devices, associated hardware, and Controlled Cryptographic Items (CCI). Proper use of this register helps prevent loss, compromise, or unauthorized access, which could impact national security.

Key Sections and Fields on DA Form 2011-1

The form includes structured columns for precise tracking:

  • Short Title — Nomenclature or identifier of the equipment.
  • NSN/MCN — National Stock Number or Management Control Number.
  • End Item — Associated higher-level system or equipment.
  • ALC — Accountability Legend Code (e.g., ALC 1 for serial-number accountability, ALC 2 for quantity accountability).
  • Account No. — COMSEC account identifier.

Transaction columns typically capture:

  • Serial numbers (begin/end).
  • Receipt, transfer, or loan data.
  • Dates (YYYYMMDD format).
  • Duration of loans.
  • Quantity on hand and balanced totals.

Examples in TB 380-41 illustrate entries for ALC 1 (serial-numbered) and ALC 2 (quantity) items.

Who Uses DA Form 2011-1?

  • COMSEC Custodians and alternate custodians at using units.
  • Hand Receipt Holders authorized by commanders.
  • Units maintaining sub-accounts or operational COMSEC equipment.
  • Personnel involved in inventories, transfers, or destruction reporting.

Only properly cleared and appointed personnel should handle these records. Commanders appoint custodians in writing.

How to Properly Complete and Maintain the Form?

  1. Enter equipment details at the top for each item or group.
  2. Record all transactions chronologically with accurate dates and serial numbers.
  3. Maintain running balances for quantity on hand.
  4. Use the form alongside other records like DA Form 2653-E (Daily Shift Inventory) and SF 153 (COMSEC Material Report).
  5. Retain records per AR 380-40, TB 380-41, and unit SOPs for audits and inspections.

Digital/electronic versions (e.g., 2011-1-E) may be authorized in some systems, but always verify with current TB 380-41 guidance.

Integration with COMSEC Accountability Procedures

DA Form 2011-1 fits into the larger CMCS framework managed by the U.S. Army Communications-Electronics Command (CECOM) Software Engineering Directorate (CSD) and other elements. It supports:

  • Inventories — Semi-annual (SAIR), change-of-custodian (CCIR), and daily checks.
  • Transfers and Hand Receipts — Document movement between accounts or users.
  • Destruction — Related forms (e.g., DA Form 2011 for aids) require signatures and witnesses for destruction.
  • Incident Reporting — Helps identify discrepancies that may require reports.

Units must follow AR 380-40 (Safeguarding and Controlling Communications Security Material) and TB 380-41 for full procedures.

Best Practices for U.S. Army Units

  • Conduct regular physical inventories and reconcile with the register.
  • Store the form and related COMSEC records securely in approved facilities.
  • Train all hand receipt holders on accountability responsibilities.
  • Coordinate with higher headquarters COMSEC managers for resupply or turn-in.
  • Use the official PDF from Army Publishing Directorate for current, compliant versions.

Maintaining accurate DA Form 2011-1 records demonstrates due diligence in protecting sensitive COMSEC equipment and supports mission readiness.
