Statistics are only one way to tell the story of the approximately 1.4 million servicemen and women who've been to Iraq and Afghanistan.
According to a study published in the New England Journal of Medicine, 86 percent of soldiers in Iraq reported knowing someone who was seriously injured or killed there.
28 percent were responsible for the death of a noncombatant.
One in five Iraq veterans return home seriously impaired by post-traumatic stress disorder.
