"Van Riper gained notoriety after the Millennium Challenge 2002 wargame. He played the Red Team opposing force commander, and easily sank a whole carrier battle group in the simulation with an inferior Middle-Eastern "red" team in the first two days."

There's more but, yeah, there it is. He was my battalion commander back in the day.
