From foxholes and trenches, generations of young medics and corpsmen have willingly sprinted into enemy fire to save the lives of their fellow soldiers. Some paid the ultimate price, and many were never recognized for their selfless heroism. From the Revolutionary War to the wars in Afghanistan and Iraq, their stories reflect the proud history of America's military medical corps and its pioneering contributions, which include the ambulance, sanitary hospital design, emergency surgical techniques, MASH units, and medical evacuation by helicopter (medevac). America's military medical corps adopted advances in medical science--such as blood transfusions, antibiotics, and antiseptic surgical procedures--field tested them in battle, adapted them, and proved their value. Here are accounts of boundless courage, compassion, and resourcefulness from America's forgotten heroes. But to the fighting men and women whose lives they have saved, they are battlefield angels.
