Abstract: Disclosed is a modular advanced technology -marksmanship proficiency (MAT-MP) system. The MAT-MP system provides marksmanship instructors with a robust and reconfigurable set of technological tools to quickly diagnose and remediate deficiencies in marksmanship skill at a live-fire range. The system diagnoses the shooter's performance using an array of sensors and an optic camera, all placed on the shooter's weapon, to continuously monitor and record his/her performance during weapon fire. Data output by the sensors and optic camera is gathered by the MAT-MP system's weapon-mounted control device and sent wirelessly to an instructor station, typically a tablet, laptop computer or the like. The MAT-MP coach software running on the instructor's computer presents a summarized analysis of the shooter's performance as well as provides the instructor the ability to view the raw sensor data graphically.
