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. 4. MCCLL formal FY26 collections include (primary Marine Corps commands impacted and scheduling in parenthesis): 4.a. Marine Rotational Force Darwin (MRF-D) 25.3 (I Marine Expeditionary Force [MEF] and Major Subordinate Commands [MSCs]: Quarter [Q] 1) 4.b.

Group 1-2 Unmanned Aerial Systems (UAS) (All MEFs and their MSCs, all MEUs and their MSEs, MARFORRES and its MSCs, TECOM, DC CD&I, MCWL, DC I&L, MARCORLOGCOM, MARCORSYSCOM: Q4) 4.m. 3d MLR (III MEF, 3d MARDIV, MCWL, DC CD&I, 3d MLR and its MSEs, MCB Hawaii: Q4) 4.n.

Establishment of Littoral Craft Companies (All MEFs, MARFORRES, 4th MARDIV, 4th Assault Amphibian Battalion [AAB], DC CD&I, TECOM: Q4) 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, [email protected] 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 [email protected]. 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. 8. Release authorized by Lieutenant General Benjamin T. Watson, Commanding General, Training and Education Command.//
