Christopher James Speer (September 9, 1973 – August 6, 2002) was a United States Army combat medic and an armed member of a special operations team who was killed during a skirmish in Afghanistan on July 27, 2002. Speer, who was not wearing a helmet at the time because the mission called for indigenous clothing, suffered a head wound from a grenade and succumbed to his injuries approximately two weeks later. Omar Khadr was charged and convicted of throwing the grenade that killed Speer.
