SAN DIEGO (AP) — A leading Jewish organization and others outraged by a photo showing Marine snipers in Afghanistan posing with a logo resembling a notorious Nazi symbol are demanding President Barack Obama order an investigation and hold the troops accountable.

The Marine Corps has said it does not plan any discipline because there was no malicious intent. The Marines mistakenly believed the “SS” in the shape of white lightning bolts on the blue flag were a nod to sniper scouts — not members of Adolf Hitler’s special unit that murdered millions of Jews, gypsies and others, said Maj. Gabrielle Chapin, a spokeswoman at Camp Pendleton, Calif.

The Marines are no longer with Charlie Company, 1st Reconnaissance Battalion, out of the base north of San Diego, and Chapin said she did not know if they had left the Corps.

Military officials learned of the photograph in November and investigated immediately. It later surfaced on a blog of a military weapons company.

In the September 2010 photo taken in the Sangin district of Helmand province, Marines with guns pose in front of an American flag above a dark blue flag with the “SS” letters.
