US troops injured in Iraq have required limb amputations at twice the rate of past wars, and as many as 20 percent have suffered head and neck injuries that may require a lifetime of care, according to new data giving the clearest picture yet of the severity of battlefield wounds.

The data are the grisly flip side of improvements in battlefield medicine that have saved many combatants who would have died in the past: Only 1 in 10 US troops injured in Iraq has died, the lowest rate of any war in US history.

But those who survive have much more grievous wounds. Bulletproof Kevlar vests protect soldiers’ bodies but not their limbs, as insurgent snipers and makeshift bombs tear off arms and legs and rip into faces and necks. More than half of those injured sustain wounds so serious they cannot return to duty, according to Pentagon statistics.

Much attention has focused on the 1,000-plus soldiers killed in Iraq, but the Pentagon has released little information on the 9,765 soldiers injured as of this week.

UPDATE:  And because we are a compassionate country, this is how we treat the maimed and damaged.  (Thanks to Jessica Wilson for the pointer.)
