In any earlier war, Army Master Sgt. Todd Nelson likely would soon have been dead, if not killed instantly, on a Kabul street surrounded by the flaming wreckage of his vehicle and the scattered remains of the suicide bomber who had done this to him.
The grim truth of modern warfare is that it is a tremendous driver of medical innovation, from on-the-scene trauma treatment to the laborious process of rebuilding shattered bodies almost from scratch.

U.S. troops wounded in Afghanistan and Iraq have a 90 percent chance of survival.
In Vietnam and even the Gulf War just 76 percent of the wounded survived.
Nelson, 40, had a fractured skull and crushed facial bones; his nose, right eye and ear were gone; burns covered more than 18 percent of his body. He was unconscious for six weeks, waking up in the burn unit of the state-of-the-art Brooke Army Medical Center in Fort Sam Houston, Texas, after being evacuated aboard what was basically a flying ICU.
Today, Nelson has a prosthetic blue eye and a prosthetic ear. Reconstructive surgery and skin grafts have made his face as whole as today's technology allows.
As the 10th anniversary of the Iraq war approaches, the military's medical services have developed an impressive array of improvements in front-line first aid; significant improvements in diagnosing and treating traumatic brain injuries; radical advances in artificial limbs, so much so that soldiers who have lost legs or arms have returned to active duty; and some techniques that smack of science fiction -- the regeneration of skin from the patient's own stem cells and body fat, even spray-on skin harvested from the patient's own skin cells.

Col. Robert Hale, who specializes in reconstructive surgery at the Army Institute of Surgical Research in San Antonio, recently told science writers that the wars in Iraq and Afghanistan may be remembered for the advances in regenerative medicine they prompted and expressed the hope that "within 20 years we'll be able to re-grow an entire face from the patient's own cells."
The insights learned from keeping wounded warriors like Sgt. Nelson alive and rebuilding his face are quickly being disseminated in the emergency rooms, ambulances and surgical departments of civilian medicine.
Those advances must not be squandered because they came at a high price -- 5,200 American dead and more than 50,000 wounded.
The medical knowledge we've gained in some small measure justifies their sacrifice.
