Fort Hood , Texas ( CNN ) -- A judge on Tuesday granted a defense request to delay the Article 32 hearing of Maj. Nidal Hasan , the Army psychiatrist accused of killing 13 people in a November shooting spree at Fort Hood , Texas , until October . Hasan made his first courtroom appearance in connection with the case Tuesday . The hearing was the first part of an Article 32 hearing , the military procedure similar to a civilian grand jury , for the case being built against him by the Army . Hasan uses a wheelchair after gunshot wounds he sustained in the November 5 incident . He wheeled himself into the courtroom , wearing his Army fatigues . He wrapped himself in a blanket during the hearing . Hasan offered short answers to questions posed by the judge , Investigating Officer Col. James Pohl . Asked whom he wanted to represent him , he named his three attorneys . Hasan appeared calm throughout the proceeding , at one point cracking a smile while speaking with his attorney . Security for the hearing was tight , with nearby streets blocked off and bomb-sniffing dogs present . Reporters went through two layers of security . The only people present at the hearing besides the media were legal assistants . Most of the hearing revolved around evidence Hasan 's attorneys have asked for in the discovery process , the routine practice that is part of every criminal case , be it civilian or military . Hasan 's lead civilian attorney , John Galligan , a retired colonel with three decades of experience as an Army lawyer , has asked for everything from DNA test results to crime scene video to copies of investigations of the shooting ordered by President Barack Obama . Last week , the Army delivered 2,000 pages of documents to Galligan , but many of the items he requested are still not available to the defense team , Galligan said . For example , dozens of shots were fired that day on the sprawling Army base in central Texas . Galligan asked for `` records of the measured angle of each trajectory , showing the trajectory from each bullet hole to the shooter 's position . '' The Army said in a court document filed in response , `` There are no documents of files of items responsive to the defense request at this time . '' Galligan also has asked for all e-mails between Hasan and Yemeni-American cleric Anwar al-Awlaki . Prosecutors agreed Tuesday to release them to the defense . Defense attorneys also are requesting some classified documents . Prosecutors said Tuesday they are in the process of attempting to de-classify them . Pohl granted defense attorneys ' request for the delay , although prosecutors said they would be ready to present evidence at the Article 32 hearing in July . Galligan 's request makes clear that his defense case will delve into what happened before November 5 . Hasan 's lawyer has asked for reports of inappropriate or substandard work by Hasan while he was training at Walter Reed Army Medical Center in Washington . Unlike a civilian grand jury hearing , Article 32 hearings involve both the prosecution and the defense , and witnesses are questioned by both sides . Galligan earlier told CNN that since the entire defense legal team , which includes Galligan and two military lawyers , has only met with Hasan once , the team needs more time to help build a case for him . CNN 's Larry Shaughnessy contributed to this report .
