The contents of this section are summarized in Table 1.

United States

The United States pioneered several battlefield innovations, notably the development of Mobile Army Surgical Hospital (MASH) units. These facilities revolutionized trauma care by enabling rapid intervention. Positioned near combat zones, they provided immediate surgical care to wounded soldiers. A typical MASH unit was designed to be highly mobile and self-sufficient, enabling swift deployment and setup in various terrains. Each unit comprised approximately 10 surgeons, 12 nurses, and 200 enlisted personnel, capable of treating up to 200 patients. The hospital was equipped with inflatable shelters that provided insulated areas for patient care. These shelters required power systems to supply utilities such as heating, cooling, and air filtration. Designed for rapid assembly and disassembly, MASH units could relocate frequently to follow the front lines, ensuring timely medical intervention for wounded soldiers. Within a MASH unit, military surgeons were organized to maximize efficiency and responsiveness. They were divided into teams, each responsible for specific types of surgical procedures, such as trauma, orthopedic, or abdominal surgery. To maintain continuous operations, surgical teams worked in rotational shifts, providing 24/7 availability for emergency procedures. Surgeons collaborated closely with anesthesiologists, nurses, and medics to administer comprehensive perioperative care, from initial assessment to postoperative recovery (Fig. 1) [1]. The organizational structure and operational strategies of MASH units have improved the survival rates of wounded soldiers by reducing mortality and morbidity during conflicts. The legacy of MASH units continues to influence modern military medicine, underscoring the importance of mobility, rapid response, and multidisciplinary collaboration in combat medical care [2,3].

The Korean War (1950–1953) marked the first large-scale use of helicopters for medical evacuation (MEDEVAC), significantly improving survival rates for wounded soldiers. The Bell H-13 Sioux helicopter (Bell Helicopter), recognizable by its bubble-shaped cockpit and external stretcher pods, became the symbol of rapid battlefield evacuation. Before helicopters were used, wounded soldiers relied on ground transportation, often taking hours or even days to reach a surgical facility. Helicopters reduced this time to minutes, lowering mortality rates. The war reinforced the importance of treating wounded soldiers within the first hour of injury. Helicopter evacuation ensured that casualties reached MASH units in time for life-saving surgery. Early in the conflict, helicopters primarily transported patients without in-flight medical care. Later, medics joined evacuations to stabilize patients during transport. MEDEVAC operations contributed to a dramatic decrease in battlefield mortality; the fatality rate among wounded soldiers dropped to around 3%, compared to over 4% in World War II. The Korean War MEDEVAC system laid the foundation for future combat medical evacuation, influencing Vietnam War practices and modern military medical doctrine. The success of helicopter evacuations in Korea demonstrated that air transport is essential for modern military medicine, revolutionizing battlefield casualty management [2,3].

The helicopter evacuation system employed by MASH units marked a major advancement, enabling the rapid transport of critically injured soldiers from the front lines to hospitals and significantly improving their survival prospects. These developments heavily influenced trauma medicine and were integrated into civilian medical practices following the war.

During the Korean War, advancements were also made in vascular surgery, primarily due to the high incidence of vascular injuries and the need for rapid, effective interventions. The introduction of the MASH system was key to these advancements. The proximity of MASH units to the front lines allowed surgeons to perform vascular repairs promptly, reducing the time between injury and treatment. This immediacy was crucial in preventing complications such as hemorrhage, infection, and limb loss. Surgeons developed and refined techniques for repairing blood vessels, including end-to-end anastomosis and the use of vein grafts. These methods improved the success rates of vascular surgery and contributed to better patient outcomes. The collaborative environment within MASH units, involving surgeons, anesthesiologists, nurses, and support staff, ensured comprehensive care for patients with vascular injuries. This teamwork facilitated the development of standardized protocols for managing such injuries. Innovations including helicopter evacuation, whole blood transfusions, and antibiotic treatments contributed to reducing mortality rates among treated soldiers to as low as 3%. These pioneering techniques established the groundwork for contemporary emergency medicine [4–6].

Colonel Benjamin L. McGaw, a US Army surgeon, is renowned for his contributions to medical care on the battlefield, especially regarding the treatment of severe burns and the extensive application of antibiotics. Dr. Michael E. DeBakey, a distinguished cardiovascular surgeon, played a key role in advancing military medical technology, although his influence was more pronounced in subsequent military conflicts [7].
