GENTEXT/Remarks/1.  This is a Deputy Commandant, Combat Development
and Integration message.  This message announces the fiscal year
(FY) 2026 mission essential task/mission essential task list
(MET/METL), training management team (TMT), and training and
readiness (T&R) manual review working group (WG) battle rhythm in
support of service capabilities implementation and has been
coordinated with Policy and Standards Division, Training and
Education Command.  Objective for FY-26 reviews is in adherence to a
deliberate three-year review schedule ensuring development,
refinement, and alignment actions are synchronized with unit mission
statements, METs/METLs and T&R manuals.

2.  Defense Readiness Reporting System (DRRS) is the authoritative
data source system for readiness reporting and mission assessments.
All Marine Corps reporting organizations will use DRRS to create and
submit MET-based readiness reports.  The FY-26 battle rhythm
provides policy and procedures for the development, review, and
validation of METs/METLs and T&R standards required to support
Marine Corps units, major subordinate commands, and supporting
establishments readiness reporting.

3.  METL working groups will focus on planning, synchronizing, and
identifying necessary and evolving METs associated with mission
requirements, that correspond and align with unit mission
statements and table of organization and equipment.

4.  Ground and Aviation T&R manuals will focus on developing
training standards that support the accomplishment of Marine Corps
warfighting capabilities and determine baseline/advanced
standards that produce quantifiable outputs for core and core plus
METs. 

5.  Reporting organizations not listed within the FY-26 schedule are
 encouraged to contact the points of contact to determine
feasibility, scope, and forum for out-of-cycle MET/METL/T&R reviews.

6.  Working group participation is critical for the successful
review and validation of warfighting capabilities, METLs and T&R
standards.  Marine Corps principal advisor stakeholders are required
to provide lead action officers / subject matter experts (AOs/SMEs)
to participate in pre, during, and post WG development actions.

7.  Physical in-person MET/METL, T&R manual and TMT reviews are
encouraged based on the community, classification, and organization,
but when feasible, virtual reviews can be conducted.  Changes to
unit mission requirements and mission statements will be addressed
at METL review WGs as required.  Dates and locations for reviews,
and solicitation for AO/SME participation for all reviews will be
published via separate correspondence (SEPCOR).  Any changes to the
dates identified within paragraphs 8.a through 8.i will be published
via SEPCOR.
