Washington (CNN) - Defense Secretary Robert Gates is ordering a number of changes to address problems discovered by a review of the military after the deadly shooting at Fort Hood Army Post last November.
Thirteen people died in the shooting at the sprawling base in central Texas. Army psychiatrist Maj. Nidal Hasan is charged in the case. He has not yet entered a plea.
After the shooting, a number of investigations and reviews were launched. One of the reviews focused on the lessons learned from the incident. In April, after releasing a preliminary report from the review, Gates implemented some two dozen of the recommendations. Friday he released the final "Lessons Learned" review and ordered implementation of most of the other recommendations from that review.
