Aaron Alexis, alleged Navy Yard shooting gunman, showed “pattern of misconduct” in military

He then spent four years working as an aviation electrician’s mate, most recently at the naval air station in Fort Worth, Texas. Military records show “a pattern of misconduct,” though in January 2011 Alexis received an honorable discharge.

In all likelihood, what Alexis got was a general discharge. Basically it means he concluded his service, but there were enough problems in his record to prevent a real honorable discharge and would not allow him to re-enlist.
