A disturbing video making its way to millions of people online and in the news shows a soldier tossing what appears to be a yelping puppy end-over-end off a cliff in Iraq.

While we thank the Marine Corps Base Hawaii (MCBH) for launching a full investigation into this apparent act of extreme animal abuse, we want to make sure that the punishment reflects the serious nature of this violent act. The MCBH should require that the suspects appear before a court-martial and should seek the most severe penalties under the Uniform Code of Military Justice, including discharge from the Corps, for the suspects if they are convicted. The U.S. Marine Corps should also establish a zero-tolerance policy for cruelty to animals, which would help ensure that this is the last time that the U.S. will suspect any of its brave men and women of abusing a defenseless animal during their service to America.
