1. The purpose of this MARADMIN is to announce the Irregular Warfare and Competition (IW/C) Lessons Learned SharePoint topic pages. These topic pages have been created in collaboration with the Marine Corps Center for Lessons Learned (MCCLL), Command Data Analytics Office (CDAO), Training and Education Command (TECOM); and the Ground Combat Element Division (GCED), Capabilities Development Directorate, Combat Development and Integration (CD&I). 2. Background. As directed by the references, the Service is required to incorporate IW-relevant Service lessons learned and best practices into Service doctrine, education, training, and concepts. Analyzing specific IW/C lessons learned across the doctrine, organization, training, materiel, leadership and education, personnel, facilities, and policy (DOTMLPF-P) areas allows the Marine Corps to continuously learn and improve readiness and accomplish assigned missions. To achieve this, MCCLL has developed an IW/C topic page on its NIPRNET SharePoint site that consolidates and allows easy access to all IW/C MCCLL unit after action reports, topic discussion recommendations, and other relevant documents to enable capability development across DOTmLPF-P. The MCCLL IW/C topic page also contains links to other related topic pages such as those established for Operation Enduring Freedom, Operation Iraqi Freedom, foreign humanitarian assistance missions and Information Environment Operations. Additionally, GCED has developed an IW/C page that contains directives, policies, and other guiding documents for force development. 3.
