During World War I, combat medics learned how to prioritize the wounded and the concept of triage eventually became standard practice in U.S. hospital emergency rooms; from World War II came mass production of penicillin and the modern day blood-banking system; wound adhesives debuted during the Vietnam War; Operation Desert Storm saw the advent of hemostatic bandages; and over the past twelve years combat injuries sustained in Iraq and Afghanistan have led to immeasurable advancements in medical technology as everything from tourniquets to prosthetics have been improved to meet the needs of service members on the front lines.
