U.S. Army regulations require all soldiers to undergo annual audiometric testing to maintain hearing readiness. The standard method of monitoring hearing in the DoD is via multi-person testing in sound-treated booths using the Defense Occupational and Environmental Health Readiness System-Hearing Conservation. COVID-19 significantly hindered the standard method, resulting in alarming declines in hearing readiness. In response, the Army Hearing Program initiated a pilot program to use boothless audiometers to supplement standard methods to increase hearing readiness. ⋯ Significant reductions in patient encounters as a direct result of the COVID-19 pandemic have led to innovative solutions leveraging boothless audiometers. While this has aided the primary mission to maintain a medically ready force, innovations from this endeavor highlight several additional improvements relative to current standards of care that should be considered for permanent inclusion in DoD Hearing Conservation Programs.

The helmet is an ideal platform to mount technology that gives U.S. Soldiers an advantage over the enemy; the total system is recognized quantitatively as head-supported mass (HSM). The stress placed on the head and neck is magnified by adding mass and increasing the center of mass offset away from the atlanto-occipital complex, the head's pivot point on the spine. Previous research has focused on HSM-related spinal degeneration and performance decrement in mounted environments. The increased capabilities and protection provided by helmet systems for dismounted Soldiers have made it necessary to determine the boundaries of HSM and center of mass offset unique to dismounted operations. ⋯ The presented work is the first of its kind specifically for dismounted Soldiers. Research is underway to validate these limits and develop dismounted injury risk guidance.

U.S. Military healthcare providers increasingly perform prolonged casualty care because of operations in settings with prolonged evacuation times. Varied training and experience mean that this care may fall to providers unfamiliar with providing critical care. Telemedicine tools with audiovisual capabilities, artificial intelligence (AI), and augmented reality (AR) can enhance inexperienced personnel's competence and confidence when providing prolonged casualty care. Furthermore, implementing offline functionality provides assistance options in communications-limited settings. The intent of the Trauma TeleHelper for Operational Medical Procedure Support and Offline Network (THOMPSON) is to develop (1) a voice-controlled mobile application with video references for procedural guidance, (2) audio narration of each video using procedure mentoring scripts, and (3) an AI-guided intervention system using AR overlay and voice command to create immersive video modeling. These capabilities will be available offline and in downloadable format. ⋯ Developing a platform to provide real-time, offline support will deliver the benefits of synchronous expert advice within communications-limited and remote environments. Trauma THOMPSON has the potential to fill an important gap for clinical decision support tools in these settings.

The Cohesion Assessment Team (CAT) provides battalion and brigade command teams with actionable insight into the climate of their unit and the presence of certain harmful behaviors. This assessment, initiated by the Vice Chief of Staff of the Army and initially managed by the Headquarters Department of the Army's People First Task Force, employs a framework from the Center for Army Professional Leadership to structure data and findings. ⋯ The CAT focuses on providing leaders at brigade and below with relevant and actionable information to help inform their internal decision-making to improve their unit's climate. This capability is distinct in many ways, including its non-attributional systems focus and its methodical approach to quickly collecting and triangulating multiple data points. Additionally, the CAT helps leaders identify areas under their control that will impact unit climate, similar to the feedback that training events provide on unit readiness. Army leadership deemed the CAT pilot a success, and responsibility for future CATs was transferred to the Training and Doctrine Command (TRADOC) in October 2022.

Use of wearable impact sensor devices to quantitatively measure head impact exposure remains largely unstudied in military-style martial arts training and combat sports, particularly at the beginner levels. The baseline frequency and severity of head impact exposure during introductory military-style martial arts trainings, such as combatives training, is valuable information for developing future programs of instruction and exposure monitoring programs. The purpose of this study was to describe head impact exposures experienced during introductory combatives training (a boxing course) at U.S. Military Academy. ⋯ Compared to other high-risk sports at Service Academies, head impacts from beginner boxing were of similar magnitude to those reported for Service Academy football and slightly lower than those reported for Service Academy rugby. Based on these preliminary data, the risk profile for introductory military-style martial arts training, such as boxing or combatives, may be similar to other contact sports like football and rugby, but further research is required to confirm these findings and understand the effects of the exposures in a shorter duration.
