"These guys play stupid every time they're asked a question about it, they pretend like they have no clue," said Shawn Manning, who was shot six times that day at Fort Hood. Two of the bullets remain in his leg and spine, he said.
"It was no different than an insurgent in Iraq or Afghanistan trying to kill us," said Manning, who was twice deployed to Iraq and had to retire from the military because of his injuries.
An Army review board initially classified Manning's injuries as "combat related," but that finding was later overruled by higher-ups in the Army.
Manning says the "workplace violence" designation has cost him almost $70,000 in benefits that would have been available if his injuries were classified as "combat related."
"Basically, they're treating us like I was downtown and I got hit by a car," he told ABC News.
For Alonzo Lunsford, who was shot seven times at Fort Hood and blinded in one eye, the military's treatment is deeply hurtful.
"It's a slap in the face, not only for me but for all of the 32 that wore the uniform that day," he told ABC News.
Lunsford's medical records show his injuries were determined to be "in the line of duty" but neither he nor any of the other soldiers shot or killed at Fort Hood is eligible for the Purple Heart under the Department of Defense's current policy for decorations and awards.
Army Secretary McHugh says awarding Purple Hearts could adversely affect the trial of Major Hasan.
"To award a Purple Heart, it has to be done by a foreign terrorist element," said McHugh. "So to declare that soldier a foreign terrorist, we are told, I'm not an attorney and I don't run the Justice Department, but we're told would have a profound effect on the ability to conduct the trial."
Members of Congress, including the chairman of the House Homeland Security committee, Rep. Michael McCaul, R-Texas, say they will introduce legislation to force the military and the Obama administration to give the wounded and dead the recognition and honors they deserve.
"It was clearly an act of terrorism that occurred that day, there's no question in my mind," McCaul told ABC News. "I think the victims should be treated as such."
Former Sgt. Munley says she now believes the White House used her for political advantage in arranging for her to sit next to Michelle Obama during the President's State of the Union address in 2010.
Munley says she has no hesitation now speaking out against the President or taking part in the lawsuit, because she wants to help the others who were shot that day and continue to suffer.
"We got tired of being neglected. So this was our last resort and I'm not ashamed of it a bit," said Munley. She is also raising money for a movie about Fort Hood, and says some of the proceeds will go to the victims.
