Battlefield medicine, also called field surgery and later combat casualty care, is the treatment of wounded combatants and non-combatants in or near an area of combat. Civilian medicine has been greatly advanced by procedures that were first developed to treat the wounds inflicted during combat. With the advent of advanced procedures and medical technology, even polytrauma can be survivable in modern wars. Battlefield medicine is a category of military medicine.
Chronology of medical advances on the battlefield
- During the Battle of Shrewsbury in 1403, Prince Henry had an arrow removed from his face using a specially designed surgical instrument.
- Ambulances or dedicated vehicles for the purpose of carrying injured persons. These were first used by Spanish soldiers during the Siege of Málaga (1487).
- French military surgeon Ambroise Paré (1510–90) pioneered modern battlefield wound treatment. His two main contributions to battlefield medicine are the use of dressing to treat wounds and the use of ligature to stop bleeding during amputation.
- American Revolutionary War: Many surgeons during this time were not licensed practicing physicians, 400 out of 3,500 doctors were fully licensed, in fact only two universities offered medical degrees which was King's College in New York, and the College of Philadelphia. At this time there were very few doctors that had equal knowledge as their European counterparts. They also were not able to produce many remedies for illnesses, only scurvy, malaria, and smallpox. Most deaths occurred not from battle injuries, but from surgeries because of not knowing the proper techniques and not having proper sterilization. One study shows that around 50% of surgeries were fatal.
- The practice of triage pioneered by Dominique Jean Larrey during the Napoleonic Wars (1803–1815).
- Russian surgeon Nikolay Ivanovich Pirogov was one of the first surgeons to use ether as an anaesthetic in 1847, as well as the very first surgeon to use anaesthesia in a field operation during the Crimean War.
- American Civil War surgeon Jonathan Letterman (1824–72) originated modern methods of medical organization within armies.
- Advances in surgery - especially amputation, during the Napoleonic Wars and First World War on the battlefield of the Somme.
- The first practical method for transporting blood, by Norman Bethune during the Spanish Civil War.
- The establishment of fully equipped and mobile field hospitals such as the Mobile Army Surgical Hospital was first practiced by the United States in World War II. It was succeeded in 2006 by the Combat Support Hospital.
- The use of helicopters as ambulances, or MEDEVACs was first practiced in Burma in 1944. The first medivac under fire was done in Manila in 1945 where over 70 troops were extracted in five helicopters, one and two at a time.
- The extension of emergency medicine to prehospital settings through the use of emergency medical technicians.
- Wound VACS, modified burn management protocols, liberal use of Factor 7 and other contributions from pioneers like Maj James Pollock, Major Mark Rasnake and Col Ty Putnum define the spirit of the Combat Medics of every AEF deployment cycle.
- The use of remote Physiological Monitoring Devices on soldiers to show vital signs and biomechanical data to the medic and MEDEVAC crew before and during trauma. This allows medicine and treatment to be administered as soon as possible in the field and during extraction.
The term "Meatball surgery" is a term used in battlefield medicine to refer to surgery that is meant to be performed rapidly to stabilize the patient as quickly as possible.
Current Battlefield Medicine used by the U.S. Military
- Over the past decade combat medicine has improved drastically. Everything has been given a complete overall from the training to the gear. In 2011, all enlisted military medical training for the U.S. Navy, Air Force, and Army were located under one command, the Medical Education and Training Campus (METC). After attending a basic medical course there, similar to a civilian EMT course these medical professions go on to advanced training in Tactical Combat Casualty Care 
Tactical Combat Casualty Care
Today, TCCC is quickly becoming the standard of care for the tactical management of combat casualties within the Department of Defense and is the sole standard of care dually endorsed by both the American College of Surgeons and the National Association of EMT’s for casualty management in tactical environments. 
- TCCC is built around three definitive phases of casualty care:
- Care Under Fire: Care rendered at the scene of the injury while both the medic and the casualty are under hostile fire. Available medical equipment is limited to that carried by each operator and the medic. This stage focuses on a quick assessment, and placing a tourniquet on any major bleed.
- Tactical Field Care: Rendered once the casualty is no longer under hostile fire. Medical equipment is still limited to that carried into the field by mission personnel. Time prior to evacuation may range from a few minutes to many hours. Care here may include advanced airway treatment, IV therapy, ect. The treatment rendered varies depending on the skill level of the provider as well as the supplies available. This is when a corpsman/medic will make a triage and evacuation decision. Triage
- Tactical Evacuation Care (TACEVAC): Rendered while the casualty is evacuated to a higher echelon of care. Any additional personnel and medical equipment pre-staged in these assets will be available during this phase. 
- Since "90% of combat deaths occur on the battlefield before the casualty ever reaches a medical treatment facility" (Col. Ron Bellamy) TCCC focuses on training major hemorrhaging, and airway complications such as a tension-pneumonthorax. This has driven the casualty fatality rate down drastically since the Vietnam conflict to less than 9%.
