U.S. General Killed In Afghanistan Was On First Combat Deployment

This post was last updated at 7 p.m. ET.

An attacker wearing an Afghan military uniform opened fire at service members of the NATO-led coalition in Afghanistan on Tuesday, killing a U.S. major general.

The officer's family has been notified of his death; his name is Harold Greene.

Army Chief of Staff Gen. Ray Odierno issued a note of condolence, saying of Greene and others caught by the attack, "These soldiers were professionals, committed to the mission. It is their service and sacrifice that define us as an Army."

A U.S. official tells NPR's Tom Bowman that 15 others — including a German brigadier general and other coalition forces — were wounded by one shooter using a light machine gun at the Marshal Fahim National Defense University in Kabul City.

Of the investigation into the attack, Tom reports, "Officials say they believe the shooter was an Afghan army officer, and not a Taliban infiltrator."

He adds that Greene is the first U.S. general to be killed in a war zone since the Vietnam War.

A Department of Defense posting notice from January said Greene had been the deputy for acquisition and systems management in the office of the assistant secretary of the Army in Washington, D.C., when he was assigned to help oversee the "Combined Security Transition Command" in Afghanistan.

According to an Army biography, Greene was originally from upstate New York, and he had advanced degrees from both Rensselaer Polytechnic Institute and the University of Southern California. He had worked in several posts related to the service's equipment, engineering, and logistics.

"Gen. Greene was on his first combat deployment to Afghanistan, in his first combat deployment ever," according to Tom, who adds, "Greene was an engineer by training."

Tom reports that this insider attack is one of the bloodiest during the Afghan war, and that the major general is the highest-ranking official to be killed during the war.

The New York Times reports:

CNN, quoting the Afghan military, says the shooter was killed by Afghan soldiers.

Update at 12:47 p.m. ET. A Pernicious Threat:

During his regularly scheduled press briefing, Rear Adm. John Kirby, Pentagon press secretary, said that while the investigation into the incident is just beginning, there is no reason to believe that the suspected shooter was anything but a part of the Afghan military.

Kirby said that as terrible as today was, insider attacks have been decreasing in Afghanistan. He said that at the time of the attack, security measures intended to urb insider attacks had been instituted.

"The insider threat is a pernicious threat that's difficult to ascertain," Kirby said.

Kirby was asked if this incident would diminish trust between coalition forces and the Afghan military.

Kirby said no. He said that the Afghan military has had an otherwise very good year, helping to secure two big elections.

"This is a security force that grows stronger by the week," Kirby said.

Update at 11:31 p.m. ET. The Location Of The Shooting:

In a statement, ISAF says it misnamed the location of the shooting. It took place at the Marshal Fahim National Defense University in Kabul City, not Camp Qargha as it originally reported.

We've updated this post to reflect that information.

Update at 10:50 a.m. ET. German Brigadier General:

Quoting the German military, The Associated Press reports a German brigadier general was injured in the attack.

The AP also has some background on the officer academy:
