(October 18, 2012)--Many of the wounded soldiers and families of those killed in the 2009 Fort Hood shooting rampage say they aren't the benefits they need because the government hasn't declared the massacre a terrorist attack.

A group of about 160 people affected by the shooting on the Texas Army post released a video Thursday expressing their frustration.

Staff Sgt. Shawn Manning, who was shot six times in the Nov. 5, 2009 rampage at the post's Soldier Readiness Center, says he's upset that the Defense Department has referred to the shooting as workplace violence.

Samuel Ray Jr., a former Fort Hood police officer who was on base the day of the shooting, says "workplace violence" is a disrespectful term.

"The people I saw were laying on the floor dead. They didn't have a chance or an opportunity to run. Where they fell...they died," Ray said.

"To call it 'workplace violence,' is extremely disrespectful. It's disrespectful to the people that died that day, and to the people who put their lives on the line to stop Hasan," Ray said.

Survivors in the video say soldiers injured or killed deserve fair benefits and Purple Heart eligibility, but they say that won't happen until the shooting is declared a terrorist attack.

On October 10th, Rep. John Carter and Rep. Michael McCaul sent letters to the Secretary of Defense and the Secretary of the Army. They requested better benefits and Purple Heart eligibility for soldiers injured during the shooting.

Accused gunman Maj. Nidal Hasan, an American-born Muslim, faces the death penalty if convicted in the rampage that killed 13.
