Members of the Army Reserve combat stress unit say they never wavered in their determination to serve. Several soldiers from across the country volunteered to fill the void after the shootings.
Charges against the accused gunman, Army psychiatrist Maj. Nidal Hasan, include 13 counts of premeditated murder.
He had been set to deploy with the unit before the shootings. Army officials have not said whether he knew or was targeting anyone in the unit.
