Friday marks the one year anniversary of the Fort Hood shooting, when Maj. Nidal Hasan opened fire on the base, killing 13 people and wounding dozens of others.
Officials are planning two memorial services to honor the victims. The Army will also unveil a monument.
Meanwhile, a hearing will continue later this month for Hasan, an American-born Muslim, to determine if there is enough evidence against him to go to trial.
The 40-year-old Army psychiatrist was identified by surivivors who took the stand earlier this month.
