Twenty Five - S4-E23
Other mistake: Chairman of the Joint Chiefs Admiral Fitzwallace tells Bartlet that he wants to attack targets in Qumar. The first he mentions is "the Bahji C3I" which he explains is "Communications, Command, Control and Intelligence." The explanation shows the actor John Amos flubbed his line and should have said "the Bahji 3CI", as in "C.C.C.I" or "Triple-C I." This is common governmental and military abbreviation jargon, much as the show often uses "D-triple-C" to mean the D.C.C.C. (Democratic Congressional Campaign Committee). (00:16:50)
Suggested correction: C3I is similar to C2, pronounced "C two" and commonly used in military to refer to command and control.
