On active duty, Moorman rose to the grade of major general, last serving as the Judge Advocate General of the United States Air Force, the Air Force's highest-ranking uniformed lawyer. In that position he directed an active and reserve force of more than 2,500 uniformed and civilian attorneys. He was serving in that position at The Pentagon on September 11, 2001, when terrorists attacked the United States.

He was the only judge advocate ever to serve as the senior officer aboard Looking Glass, the nation's airborne nuclear forces command post. Moorman's military decorations include the Distinguished Service Medal with oak leaf cluster, the Legion of Merit with oak leaf cluster, the Joint Meritorious Service Medal, and the Meritorious Service Medal with four oak leaf clusters. He retired from the Air Force in April 2002, after 31 years of service.
