In the unaired version of the pilot Sarah Clarke played Maj. Tisnewski's wife and mother of his infant. She was formerly of the CIA, but had left the agency to become a full-time mom and homemaker. In the version that eventually aired, the Major was not married, had no children, and was dating a female CIA agent played by Kelsey Oldershaw.
NBC gave the show a full-season order of 22 episodes but only aired 14.
The show's title is a reference to the offices along the outer edges of the Pentagon.
