The U.S. Department of Defense is implementing new policies aimed at protecting service members from brain injuries caused by blast overpressure during training and combat. The new measures, outlined in a memorandum signed by Deputy Defense Secretary Kathleen Hicks, include mandatory cognitive assessments for all new recruits by the end of 2024 and for high-risk active duty and reserve personnel by the end of 2025.
The policy is part of a broader effort to address the growing concerns over traumatic brain injuries (TBIs) linked to repeated exposure to blasts from heavy weaponry and explosives. The new guidelines also set specific stand-off distances for trainers during live-fire exercises, limit the number of people in proximity to blasts, and emphasize the use of protective equipment. These steps are designed to mitigate the risks without compromising combat readiness.
The Pentagon’s move follows reports highlighting the health risks faced by military personnel exposed to repetitive blasts, with symptoms including headaches, memory loss, and depression. The memorandum also requires the military to incorporate more simulators into training to reduce blast exposure and mandates that personnel report symptoms of blast overpressure and seek medical evaluation when needed.
The policy targets 97 military occupational specialties identified as being at increased risk of blast exposure, including roles in the Army, Air Force, Marine Corps, and Navy.Â
