Foot-borne soldiers sometimes carry out nighttime operations. It has previously been reported an elevated metabolic demand and impaired walking economy during outdoor walking on a gravel road in darkness wearing night vision goggles (NVG), compared with wearing a headlamp. The aim of the present study was to evaluate the effect of wearing NVG while walking in a hilly forest terrain and compare the results between experienced and inexperienced NVG users. ⋯ Despite that foveal vision using NVG is adequate, it appears that the mechanical efficiency during nighttime walking in hilly terrain was markedly lower while wearing NVG than with full vision, regardless of whether the soldier was an experienced or inexperienced NVG user. Moreover, the walking economy was even more affected when adding the 25-kg extra weight. It is probable that the deteriorated mechanical efficiency was partly due to the shorter step length in all three conditions with limited vision.

Blood transfusions are common during combat casualty care, aiming to address the loss of blood volume that often accompanies severe battlefield injuries. This scoping review delves into the existing military combat casualty data to analyze the efficacy, challenges, and advances in the use of massive and super-massive transfusions in the management of critically injured warfighters. ⋯ We identified 53 studies focused on blood transfusions from the Global War on Terrorism conflicts. The majority were related to transfusion ratios and the movement of blood transfusions to more forward locations. We highlight key lessons learned on the battlefield that have been translated into scientific developments and changes in civilian trauma methods.

World War I and the Thomas Splint: A Historical Review.
The Thomas splint, the first practical traction splint for femoral fractures, revolutionized the capabilities of military medicine. Its usage in WWI lowered the mortality rate from 80% to nearly 15%. Its development not only shaped modern orthopedics but also established the splint as standard equipment in hospitals worldwide.

Current literature supports a multidisciplinary approach to penicillin allergy delabeling. Our study aims to review the success rate of penicillin challenges performed at Walter Reed National Military Medical Center Allergy Clinic and assess the reaction rate associated with a direct oral challenge in low-risk patients. ⋯ Given the low rate of adverse events in this study, expansion of penicillin delabeling in the primary care setting should be considered in patients deemed to be at low risk. It is important for allergists to empower and educate their peers and push forward a movement to create a multidisciplinary approach to penicillin delabeling.

The Special Warfare Training Wing and Special Warfare Human Performance Support Group (HPSG; all-co-authors) were established in fiscal year (FY) 2019 to consolidate and oversee all Air Force Special Warfare (AFSPECWAR) training and provide embedded medical and human performance support to candidates with the goal of improving graduation rates and the longevity of the AFSPECWAR operator. The purpose of this manuscript is to assess the impact of the HPSG on AFSPECWAR graduation rates, musculoskeletal injury (MSKI) incidence, and cost. ⋯ The impact of the HPSG on attrition, MSKI incidence, and cost-of-care was not consistent across all training pipelines; however, taken together, there were no increases in attrition, and the cost of MSKI management was significantly lower.
