OPNAV INSTRUCTION 3500.38C
From: Chief of Naval Operations
Subj: UNIVERSAL NAVAL TASK LIST
Ref: (a) OPNAVINST 5215.17A
1. Purpose
a. To update the policy for Navy administration and application of the Universal Navy Task
List (UNTL).
b. The UNTL is a single source document that combines task libraries from three services:
the Navy Tactical Task List (NTTL), consisting of Navy and Coast Guard information and the
Marine Corps Task List (MCTL). This directive provides the policy for management and control
of the UNTL by the U.S. Navy (USN). MCO 3500.26B and COMDT INST 3500.1 released in
March 2020 cover the United States Marine Corps (USMC) and United States Coast Guard
(USCG) task policy.
c. This directive describes how to use the UNTL in programs and missions supporting the
National Military Strategy and Homeland Security.
d. This instruction is a complete revision and should be reviewed in its entirety.
2. Cancellation. OPNAVINST 3500.38B is hereby cancelled. This instruction parallels the
USMC MCO 3500.26B and the Coast Guard COMDTINST 3500.1 to ensure the naval services
are aligned.
3. Scope and Applicability. The UNTL combines task libraries from three Services: the NTTL
consisting of Navy and Coast Guard information and the MCTL which contains USMC specific
guidance. The tasks are no longer included in this document, but have been relocated to web
sites to improve their accessibility and visibility.
4. Responsibilities. Navy Warfare Development Command (NWDC) will serve as coordinator
and primary review authority for the UNTL.
5. Navy Task Library Site. The NTTL is available in various formats from the NWDC portal at
