Marine Corps Maneuver Squad Leader Mastery Model

This report documents the USMC Maneuver Squad Leader Mastery Model that describes the developmental path to expertise for 0311 rifle maneuver squad leaders and weapons section leaders, referenced collectively throughout this document as maneuver squad leaders. The five stage descriptive model contains key performance areas, performance indicators at different stages of development, and linkages to the decision making competencies and supporting cognitive and relational skills (CARS) for small unit leaders that were previously identified by TECOM. The purpose of the model is to provide insights into both how individuals progressively develop into high performing maneuver squad leaders and implications for what should be assessed and how during development to improve cognitive readiness with individual, unit, and organizational enhancements. The 58 interviews serving as the basis for this report were conducted at School of Infantry East (SOI E), School of Infantry West (SOI W), 1st Marine Division, 2nd Marine Division, and with members of two Reserve battalions preparing for deployment. Findings identified nine key performance areas with behavioral indicators of performance (in order of emphasis): Tactical Skills/Tactical Thinking; Character, Initiative, and Command Presence; Train, Mentor, and Develop Marines; Job Knowledge; Administration; Self Development; Communication; Self Control and Stress Management; Adaptability/Flexibility. The model will provide insight into what should be assessed during development and eventually provide insight into the effectiveness of developmental enhancements. Immediate next steps include integration of the findings into the SUDM Assessment Battery under development for TECOM to assess small unit leader decision making proficiency.
