With over 13,500 participants, the US government took over two years to design it.

The exercise pitted Iran against the US military. Washington intended to show how the US military could defeat Iran with ease.

Paul Van Riper, a three-star general and 41-year veteran of the Marine Corps, led Iranian forces in the war game. His mission was to take on the full force of the US military, led by an aircraft carrier battle group and a large amphibious landing force in the Persian Gulf.

The results shocked everyone…

Van Riper waited for the US Navy to pass through the shallow and narrow Strait of Hormuz, which made them sitting ducks for Iran's unconventional and asymmetric warfare techniques.

The idea is to level the playing field against a superior enemy with swarms of explosive-laden suicide speedboats, low-flying planes carrying anti-ship missiles, naval mines, and land-based anti-ship ballistic missiles, among other low-cost but highly effective measures.

In minutes, Van Riper emerged victorious over his superior opponent and sank all 19 ships. Had it been real life, 20,000 US sailors and marines would have died.

Millennium Challenge 2002 was a complete disaster for the Pentagon, which had spent a quarter of a billion dollars to set up the extensive war game. It produced the exact opposite outcome they wanted.
