Original story

WASHINGTON -- A video posted on YouTube shows four combat Marines urinating on the corpses of three dead men in Afghanistan, a U.S. military official told NBC News on Wednesday.

"It should be pretty easy" to identify the Marines in the video, said one official, and those involved "will be held accountable for their actions." 

The video, posted on YouTube, shows the four Marines, in full combat gear, standing in a semi-circle  over three bodies and one or two can clearly be seen urinating on the corpses.

As the video closes one of the Marines appears to say, "Golden F....... showers."

The Marines, though not identified by name, were confirmed to be a sniper team out of Camp Lejeune, N.C., U.S. military officials told NBC News. They were deployed to southern Afghanistan from early 2011 until August of 2011.

In a formal statment, a Marine Corps official said: "The actions portrayed are not consistent with our core values and are not indicative of the character of the Marines in our Corps.

At first, the Marines could not determine whether the incident took place in Iraq or Afghanistan, but it was later determned to be Afghanistan.
