In July 2002, the United States military conducted the most expensive war game in its history. The Red team commander, retired Marine Lieutenant General Paul Van Riper, sank sixteen ships including an aircraft carrier in the opening days using low-technology asymmetric tactics the doctrine had not anticipated. The exercise was halted. The fleet was refloated. The end state was scripted until the doctrine was validated.

Eight months later, the doctrine was used to execute the invasion of Iraq.

Episode 9 of The Tenth Man examines the Millennium Challenge 2002: what it was designed to test, what it actually found, and why the institution's response to a functioning mechanism was to stop it. This episode introduces the distinction between a testing mechanism and a validation exercise, and traces the difference to its consequences.
