DAF COMSEC Form 16: Daily Shift Inventory Guide (2026)

DAF COMSEC Form 16: Daily Shift Inventory Guide (2026) – The DAF COMSEC Form 16, officially titled COMSEC Account Daily Shift Inventory, is a critical document used by U.S. Air Force and Department of the Air Force (DAF) personnel to maintain strict accountability of Communications Security (COMSEC) material. This form ensures the integrity, control, and security of sensitive cryptographic items, keys, and equipment during daily operations and shift changes.

Proper use of DAF COMSEC Form 16 helps prevent losses, compromises, or security incidents that could jeopardize national security. It supports compliance with DAFMAN 17-1302-O, Communications Security (COMSEC) Operations, and related Department of Defense (DoD) and Air Force instructions on COMSEC accountability.

What Is DAF COMSEC Form 16?

DAF COMSEC Form 16 (also referred to historically as AFCOMSEC Form 16) is a standardized inventory record designed specifically for daily shift inventories in COMSEC accounts. It documents the physical accountability of COMSEC material—such as keys, cryptographic devices, and associated items—by short title/edition, quantity, and serial/accounting control number (ACN).

The form supports multi-shift operations (typically Shift 1, Shift 2, and Shift 3) and includes dedicated fields for Turnover Possession Inventory (TPI), which verifies that incoming and outgoing personnel have properly accounted for all material during shift handovers.

Key Details (Current as of 2023 Revision):

  • Form Number: DAF COMSEC 16 (DAFCOMSEC16)
  • Prescribed By: AFMAN 17-1302-O (DAFMAN 17-1302-O)
  • Revision Date: February 2, 2023 (20230202)
  • Purpose: Record daily sight inventories and shift TPIs to ensure continuous accountability of COMSEC material.

Why Is the Daily Shift Inventory Important?

COMSEC material protects classified communications and cryptographic systems essential to military operations. Strict daily and shift-change inventories:

  • Detect discrepancies immediately (e.g., missing items, unauthorized access).
  • Support two-person integrity (TPI) requirements for Top Secret or sensitive material.
  • Maintain an audit trail for monthly reviews, semiannual inventories, change-of-custodian actions, and incident investigations.
  • Comply with broader DoD information security policies under DoDM 5200.01 and Air Force COMSEC user requirements.

Failure to conduct or properly document these inventories can lead to security violations, compromised keys, or formal investigations.

How to Complete DAF COMSEC Form 16?

The form uses a tabular layout with rows for individual COMSEC items and columns for daily tracking across the month. Use only blue or black ink; never use white-out, correction tape, or erasures. Line through errors neatly, initial, and date them, then add explanatory remarks on the back if needed.

Main Fields and Instructions:

  • Short Title/Edition: Identify the COMSEC material (e.g., specific key or device designation).
  • QNTY (Quantity): Record the number of items.
  • Serial Number (or Accounting Control Number/ACN): Enter unique identifiers.
  • Safe #: Note the security container or safe where the material is stored.
  • Month/Year: Header for the inventory period.
  • Columns 1–31 (Days of the Month): Mark daily inventory status.
  • Initials: Personnel conducting the inventory sign/initial for their shift.
  • Shift 1, Shift 2, Shift 3: Designate the shift.
  • Shift TPI Fields: Record Turnover Possession Inventory results (especially required for TS/TPI material).

Best Practices for Completion:

  • Conduct a sight inventory by short title/edition, quantity, and serial/ACN.
  • Perform separate inventories for each COMSEC container when opened.
  • Incoming shift personnel verify and initial the TPI against the outgoing shift’s records.
  • Mark off destroyed or transferred items clearly and retain supporting documentation (e.g., SF 153 COMSEC Material Report).
  • Review the form monthly as required.

Local computer-generated versions of the form may be authorized in some units, but they must contain all required data elements.

Who Uses DAF COMSEC Form 16?

  • COMSEC Account Managers and Alternates — Primary responsibility for overall accountability.
  • COMSEC Custodians and Users — Perform daily and shift inventories.
  • Shift Supervisors/Personnel — In operations centers, command posts, or secure facilities with rotating shifts (e.g., 24/7 environments).
  • Witnesses — For TPI or higher-sensitivity inventories.

All personnel must hold appropriate security clearances and be trained on COMSEC handling procedures.

DAF COMSEC Form 16 supports broader accountability requirements, including:

  • Semiannual Inventory Reports (SAIR).
  • Change of Custodian/Change of Account Location inventories.
  • Destruction, receipt, and transfer reports (e.g., SF 153).
  • Integration with systems like the COMSEC Material Control System (CMCS).
