The Marine who threw a puppy over a cliff, recorded it and then posted it on YouTube is “being processed for separation” (typical military language):

The Marine Corps said Wednesday it was expelling one Marine and disciplining another for their roles in a video showing a Marine throwing a puppy off a cliff while on patrol in Iraq.

The 17-second video posted on YouTube drew sharp condemnation from animal rights groups when it came to light in March.
The clip shows two Marines joking before one hurls the puppy into a rocky gully. A yelping sound is heard as it flips through the air.
“That’s mean. That’s mean, Motari,” an off-camera Marine is heard telling the Marine who tossed the black and white dog. The off-camera Marine snickered slightly afterward.
Lance Cpl. David Motari, assigned to the 1st Battalion, 3rd Marine Regiment at Kaneohe Bay, is “being processed for separation” from the Marine Corps, the Marine Corps said in a news release. He also received unspecified “non-judicial punishment.”
