The Army would have made up that difference had I been on deployment orders or had my injuries classified as combat-related.
Unfortunately, I am not alone in my experience.
I have watched other victims and their families be denied disability benefits and treated indifferently by the Army. This has left many families suffering not just physical and emotional wounds, but financial ones as well.
Though the Army claims that the survivors of the Fort Hood attack are eligible for the same medical benefits as any service member, we are not getting the same treatment as soldiers wounded in combat.
That is part of the reason we have brought a lawsuit against the government.
But it would be a mistake to think that the terrorism designation is just about benefits.
It is also about the government acknowledging its complicity in the attack.
Before the shooting, the Army knew that the gunman was an Islamic religious extremist.
After the attack, a bipartisan Senate report concluded that the Defense Department had evidence that "Hasan embraced views so extreme that it should have disciplined him or discharged him from the military, but DoD failed to take action against him."
The FBI knew that Hasan was e-mailing with known terrorist leader Anwar al-Awlaki, asking questions about religious martyrdom and expressing support for al-Awlaki's terrorist tactics. It did nothing.
The Army also knew that Hasan was an incompetent psychiatrist who repeatedly neglected his duties.
Yet instead of investigating, disciplining or discharging him, they transferred him to my medical detachment for deployment to Afghanistan.
Congress has labeled the Fort Hood attack an act of terrorism. In the wake of the attack, an independent report commissioned by the FBI looked at ways to improve counterterrorism measures.
Even the president said the attack was inspired by "larger notions of violent jihad."
The only entities that have stubbornly refused to call it an act of terrorism are the Army and the Pentagon.
Unfortunately for those wounded in the attack, their opinions are the ones that most affect us.
Hasan's conviction would represent one step on the path toward justice.
But that journey won't be complete until the government tells the truth about the attack, provides proper support for its victims and takes measures to ensure that these mistakes won't happen again.
