Memorial honoring injured veterans under way in DC

WASHINGTON (AP) — Army Lt. Dawn Halfaker was on patrol 10 years ago in Baqubah, Iraq, when a rocket-propelled grenade tore through her military vehicle and exploded inside.

When she woke up from a coma, the West Point graduate found out her right arm was gone and her career as a military officer was over at age 24. It’s the kind of sacrifice millions of U.S. soldiers have made dating back to the American Revolution. Veterans groups say there as many as 4 million living today with the scars of war.
