The paratroopers had their assignment: Check out reports that Afghan police had recovered the mangled remains of an insurgent suicide bomber. Try to get iris scans and fingerprints for identification.

The 82nd Airborne Division soldiers arrived at the police station in Afghanistan’s Zabol province in February 2010. They inspected the body parts. Then the mission turned macabre: The paratroopers posed for photos next to Afghan police, grinning while some held — and others squatted beside — the corpse’s severed legs.

A few months later, the same platoon was dispatched to investigate the remains of three insurgents who Afghan police said had accidentally blown themselves up. After obtaining a few fingerprints, they posed next to the remains, again grinning and mugging for photographs.

Two soldiers posed holding a dead man’s hand with a finger raised. A soldier leaned over the bearded corpse while clutching the man’s hand. Someone placed an unofficial platoon patch reading “Zombie Hunter” next to other remains and took a picture.

The Army launched a criminal investigation after the Los Angeles Times showed officials copies of the photos, which recently were given to the paper by a soldier from the division.

“It is a violation of Army standards to pose with corpses for photographs outside of officially sanctioned purposes,” said George Wright, an Army spokesman. “Such actions fall short of what we expect of our uniformed service members in deployed areas.”

Wright said that after the investigation, the Army would “take appropriate action” against those involved. Most of the soldiers in the photos have been identified, said Lt. Col. Margaret Kageleiry, an Army spokeswoman.

The photos have emerged at a particularly sensitive moment for U.S.-Afghan relations. In January, a video appeared on the Internet showing four U.S. Marines urinating on Afghan corpses. In February, the inadvertent burning of copies of the Koran at a U.S. base triggered riots that left 30 dead and led to the deaths of six Americans. In March, a U.S. Army sergeant went on a nighttime shooting rampage in two Afghan villages, killing 17.

The soldier who provided The Times with a series of 18 photos of soldiers posing with corpses did so on condition of anonymity. He served in Afghanistan with the 82nd Airborne’s 4th Brigade Combat Team from Ft. Bragg, N.C. He said the photos point to a breakdown in leadership and discipline that he believed compromised the safety of the troops.

He expressed the hope that publication would help ensure that alleged security shortcomings at two U.S. bases in Afghanistan in 2010 were not repeated. The brigade, under new command but with some of the same paratroopers who served in 2010, began another tour in Afghanistan in February.

U.S. military officials asked The Times not to publish any of the pictures.

Times Editor Davan Maharaj said, “After careful consideration, we decided that publishing a small but representative selection of the photos would fulfill our obligation to readers to report vigorously and impartially on all aspects of the American mission in Afghanistan, including the allegation that the images reflect a breakdown in unit discipline that was endangering U.S. troops.”
