People for the Ethical Treatment of Animals (PETA) had posted the video in November and sent a letter to Army Secretary John McHugh, but re-publicized it again last week in the wake of a viral video of Marines allegedly urinating on corpses in Afghanistan.
Wright said the investigation is still open, and investigators have analyzed the video, which was posted on the website LiveLeak.com.
Wright said Army CID has asked for assistance from other military law enforcement agencies because some men in the video could be from other services.
“It goes without saying that the behavior displayed on the video is not in keeping with Army values,” Wright said.
