Artificial intelligence (AI) is moving from pilot programs into the routine delivery of military mental health care. Predictive models already scan Veterans Health Administration records to flag veterans at high risk of suicide; models trained on Army Study to Assess Risk and Resilience in Servicemembers data can now stratify suicide risk up to a decade after soldiers leave active service, and generative AI models are being positioned to deliver triage, peer support, and low-intensity psychological interventions. The frameworks that govern responsible military AI have not kept up. The Department of Defense Responsible Artificial Intelligence Strategy and Implementation Pathway, NATO's principles of responsible use, and allied instruments such as the United Kingdom's JSP 936 provide lifecycle assurance for AI-enabled capability, but none of them makes specific provision for the therapeutic encounter. That omission exposes service members to what this commentary terms a recognition-action gap. Systems trained predominantly on civilian data can transcribe the words of military distress accurately while misreading their clinical meaning: moral injury classified as fear-based trauma, minimized suicidality scored as low risk, routine operational vernacular flagged as threat. The risk is compounded because the boundary between clinical care and occupational capability is porous in the armed forces. The military command exception to the Health Insurance Portability and Accountability Act Privacy Rule and command notification under Department of Defense Instruction 6490.08 mean that outputs generated for care could lawfully reach deployability, security clearance, and administrative decisions, with predictable consequences for help-seeking. This commentary proposes behavioral validity, the demonstrated capability to safely manage the behavioral presentations of the population a system will actually serve, as a core governance requirement for mental health AI in defense settings. It specifies 4 conditions of use: clinically supervised pre-fielding assessment, therapeutic firewalling, moral injury and cultural competency, and meaningful human control. Defense health systems should not wait for civilian regulators to notice the gap. They are well placed to define the standard.

At the turn of the 20th century, naval physicians Raymond Spear and William C. Braisted served as Bureau of Medicine and Surgery (BUMED) medical observers during the Russo-Japanese War. Their observations highlighted protected treatment spaces and limitations of first aid during combat, informing efforts to improve casualty care at sea.

Tropical infectious disease is a recurrent threat to Force Health Protection throughout the U.S. military presence in Panama. This article recounts some of the notable contributions of the U.S. military in the discovery, treatment, and prevention of infectious diseases in hopes of informing future risk assessment and mitigation.

Moral injury in healthcare is most often discussed in relation to clinicians, but healthcare executives may also experience morally significant distress when they remain accountable for organizational outcomes without sufficient agency, information, trust, or voice. This commentary introduces accountability without agency as a potential pathway to executive moral injury. Drawing on scholarship on moral injury, moral distress, psychological safety, and organizational conditions, it examines how suppressed candor, routine bypassing of accountable executives, and persistent centralization of decision-making can harm leaders and weaken organizational coordination and resilience. Although evidence specific to healthcare executives remains limited, research among healthcare workers demonstrates that moral conflict can have consequences beyond occupational dissatisfaction. The commentary concludes that healthcare organizations can reduce these risks by aligning responsibility with decision rights, protecting executive voice, distributing strategic context, and developing leaders capable of exercising judgment in service of the mission.

Improvements in cervical endurance hold (CEH) time have been used as evidence that training interventions reduce neck pain risk in Air Force fighter pilots. This assumes that a longer hold time reflects a meaningfully lower risk of neck pain in this population, an assumption that remains unvalidated. We examine the reliability and validity evidence for the CEH and argue that its use as a surrogate for training success should be reconsidered. The CEH, known as Grimmer's test, shows strong intra-rater reliability but considerably weaker inter-rater reliability, particularly where test cessation depends on subjective examiner judgment rather than pain or exhaustion. No reliability data exist for this test in fighter pilots specifically. Validity evidence in this population was absent until a 2026 study of Royal Air Force Typhoon pilots found no significant correlation between neck flexor endurance and flight-related neck pain, despite high pain prevalence in the cohort. This is the first direct test of the assumption underlying the test's current use as an outcome measure, and it does not support that assumption. Prior evidence further suggests that neck pain in military pilots is more associated with coronal plane strength than the sagittal plane flexion this test assesses, and evidence that training cervical endurance reduces neck pain incidence remains mixed. An improvement in hold time is weak evidence that an intervention reduced neck pain risk. We recommend that the CEH be reported as a measure of endurance, not a proxy for pain outcomes, with future work evaluating coronal plane and extension-based alternatives.
