GENTEXT/REMARKS/1.  Purpose.  This MARADMIN announces the Fiscal
Year (FY) 2026 Marine Corps Lessons Learned Collection Campaign
Plan (CCP) as well as identifies other collection priorities for
Analysis and Assessments Branch, Policy and Standards Division,
TECOM.
2.  Background.  The CCP was developed in conjunction with MCCLL
Program Analysts embedded in the Fleet Marine Force (FMF),
Headquarters Marine Corps (HQMC), and Marine Corps component
commands, following the completion of a Marine Corps wide data call
for lessons learned collection topics.  The topics nominated and
selected are considered to have significant value to both the FMF
and Supporting Establishment and will provide actionable information
to influence change in doctrine; operational tactics, techniques,
and procedures; and / or be informative to HQMC and Deputy
Commandants; Training and Education Command (TECOM) Headquarters
(HQ); as well as doctrine, organization, training, materiel,
leadership and education, personnel, facilities, policy and
warfighting function stakeholders for resource application
deliberations and decisions.  Selection criteria used to evaluate
all topics included linkages to the 39th Commandant of the Marine
Corps Planning Guidance (Aug 2024), Commanding General TECOM
Training and Education 2030, and Force Design, as well as
commander identified priorities.  Topic selection criteria also
included ties to naval integration and Marine Corps operating
concepts.
3.  This CCP provides a baseline for MCCLL FY26 collection execution
and will be modified as required based on emerging events and issues
and input from HQMC, the FMF, Marine Corps component commands, and
the Supporting Establishment.  For each collection effort, MCCLL will
coordinate a feasibility of support request with those commands that
are directly impacted.  Each collection will result in a MCCLL final
report.

5.  Other collection priorities for FY26 include:
5.a.  Publishing of lessons learned trend reports at six-month
intervals.  These trend reports will provide issues and best
practices from the synthesis of information collected and
archived by Analysis and Assessments Branch (A&AB), TECOM.  The
source information is drawn primarily from unit submitted After
Action Reports (AAR), though will include other lesson learned
related products.  A trend report primary purpose is to serve as
input to issue resolution processes, as well as to inform
operational planning and leader decisions.
5.b.  Unit AARs from operations, exercises, service-level training,
Marine Corps Combat Readiness Evaluation, and home station training
events are an important and essential foundation of the MCLLP and
provide a first step in providing a threat-based understanding of
how we fight.  These detailed AARs and lessons learned reports will
continue to inform and adapt our warfighting functions, operating
concepts, and force design.  Consequently, timely submission of
AARs to MCCLL for them to be meta-tagged, stored, and made
available across the Marine Corps electronically is essential.
Using the AAR template provided on the homepage of MCCLL
unclassified and classified SharePoint sites improves the results
of the artificial intelligence and machine learning capabilities
being employed.
5.c.  Reference (b) defines the process by which TECOM identifies
service-level training trends for incorporation into the Trends
Reversal and Reinforcement Process (TRRP). This process also
facilitates the dissemination of lessons learned to improve
awareness across the FMF, enhance force generation, and improve unit
readiness.  Per ref (b), the collection and analysis of Systemic
Trends Reports (STRs) and AARs from TECOM MSCs to identify systemic
service-level trends for the TRRP are a high priority.  Per ref (a),
FMF and SE organizations can submit potential trends for TRRP
validation using the unresolved trends submission template available
on the MCCLL NIPR website (see paragraph 7) under the MCCLL Templates
dropdown menu at the top of the homepage. As appropriate, results
from these submissions will be onboarded to the TECOM HQ TRRP,
resolution courses of action will be developed and briefed at the
Assessments Working Group for decision or further recommendation.
TECOM MSC STRs can be emailed to the group mailbox,
SMB_MCCLL_OPS@usmc.mil or the message point of contact can provide
coordinating instructions. 
6.  Units are encouraged to leverage the assistance provided by
MCCLL analysts embedded with the FMF and supporting establishment.
Embedded analysts have the task to execute CCP collections, collect
and facilitate AAR submissions from their supported commands, as well
as to collect other valuable information such as exercise hotwash
briefs and unit standing operational procedure documents.  The point
of contact information for embedded analysts can be accessed on the
MCCLL SharePoint homepage.  Any command that is not directly
supported by a MCCLL analyst can contact the message point of
contact or email the group mailbox at SMB_MCCLL_OPS@usmc.mil.
7.  The Marine Corps FY26 Lessons Learned CCP with amplifying
information on each collection is found on the MCCLL NIPR website
homepage, at https://usmc.sharepoint-mil.us/sites/tecom_mccll.
The classified SIPR website can be accessed at
https://usmc.spo.microsoft.scloud/sites/TECOM_MCCLL/Pages/MCCLL.aspx.
These websites contain a vast amount of Marine Corps lessons learned
information. Along with a robust archive search function, the sites
contain topical pages of items consolidated on various subjects, as
well as libraries of MCCLL reports and unit AARs.
