Lessons Learned Branch (LLB)


The Lessons Learned Branch collects and analyzes issues, lessons, and best practices from major operations and training exercises conducted by the operating forces; collaborates with medical subject matter experts to identify Doctrine, Organization, Training, Materiel, Leadership & Education, Personnel, and Facility (DOTMLPF) gaps and potential solutions; and disseminates lessons and best practices with the Army and the Army Medical community of practice to optimize unit and Soldier performance and effectiveness.


Joint Lessons Learned Information System (JLLIS)

JLLIS is the Army’s system of record for recording and sharing of all lessons learned information. It facilitates the collection, tracking, management, datamining, collaborative resolution and dissemination of lessons. The JLLIS Global Search feature provides users the ability to search for JLLIS data across Data Types; Observations, Issues, Document Repository, Community of Practices, Collection Plans, Binders, After Action Reports (AARs), and associated uploaded files.

The LLB migrated its repository of AARs, Standard Operating Procedures (SOPs), and Tactics, Techniques, and Procedures (TTPs) to JLLIS. In addition to the documents loaded by the LLB, JLLIS provides a repository of AARs and observations from other Army medical units and Sister Services.
