E-Ring

The title of the show refers to the structure of The Pentagon, which is configured in five concentric rings, from "A" to "E", with E being the outermost ring. Before any military action can be taken anywhere in the world, the mission must be planned and approved by the most important ring of the Pentagon, the E-ring. This is where the more high-profile work is done, all operations must be legally approved and the green light given by the Joint Chiefs of Staff. The show starred Benjamin Bratt as Major James Tisnewski, a former Delta Force operator and Dennis Hopper as Colonel Eli McNulty, as officers working in the E-ring of the Pentagon in the Special Operations Division (SOD) – planning and co-ordinating covert US special operations actions around the globe.

The show struggled from the onset because it was up against ABC's Top 20 hit Lost, CBS's Top 30 hit Criminal Minds, FOX's Top 10 hit American Idol and the network's other Top 30 hit Unan1mous. Although NBC gave it an earlier time slot which led to better ratings, the show was pulled from the lineup during the February sweeps and officially canceled at the NBC upfront on May 15.

• Benjamin Bratt – Major James "JT" Tisnewski,^[2] a former Army Ranger and a Delta Force operator reassigned to the Joint Staff's Special Operations Division after 14 months in the Middle East. Four years prior to the series, he was an Operational Detachments-A Captain (as seen in "Cemetery Wind").

In "Acceptable Losses" (the series finale), after taking down a Mexican drug cartel leader who'd allegedly smuggled Al Qaeda operatives across the border on US soil, LTC Tisnewski was arrested and was last seen in pre-trial confinement at the United States Disciplinary Barracks in Fort Leavenworth, Kansas.

• Dennis Hopper – Colonel Eli McNulty,^[2] the principal staff officer of the Special Operations Division. A Vietnam War veteran and former prisoner of war with two Silver Stars, COL McNulty is still sometimes a little old-fashioned when it comes to dealing with female personnel.
