The Associated Press today reported that at least 1,000 U.S. military personnel have died in Afghanistan since the war began, a count that came more than a week after The New York Times reported that number using a different formula.

“The Associated Press bases its tally on Defense Department reports of deaths suffered as a direct result of the Afghan conflict, including personnel assigned to units in Afghanistan, Pakistan or Uzbekistan,” AP reports. “Other news organizations count deaths suffered by service members assigned elsewhere as part of Operation Enduring Freedom, which includes operations in the Philippines, the Horn of Africa and at the U.S. detention facility at Guantanamo Bay, Cuba.”

AP also adds: “The list of American service members killed in combat in Afghanistan begins with Sgt. 1st Class Nathan Ross Chapman of San Antonio, Texas. The 31-year-old career Special forces soldier ambushed on Jan. 4, 2002, after attending a meeting with Afghan leaders in Khost province. He left a wife and two children. The base where a suicide bomber killed seven CIA employees last December bears his name”
