The Marine Corps is embarking on a comprehensive study of marksmanship, spanning three fiscal years and led by the Naval Health Research Center, with support from the Office of Naval Research. This study aims to revolutionize how Marines are trained to improve their marksmanship skills, addressing issues such as shooting at night, hitting moving targets, and leading targets. It will involve the use of advanced small arms lethality trainers (ASALTs) equipped with simulation technology and adaptive artificial intelligence. The study represents a significant shift towards data-driven marksmanship training, allowing for the development of more effective and realistic training scenarios beyond traditional shooting ranges.
