> The Millennium Challenge 2002 is discredited because it had motorcycle couriers that moved at light speed handling all communications and 10' speed boats launching 19' missiles.

This is not what Wikipedia's summary describes. Now, maybe Wikipedia has the wrong summary, but according to it the challenge wasn't "discredited". By that point the exercise was over, but 13 more days were budgeted for, so the analysts requested their forces to be resurrected so they could play out the rest of the days, with artificial restrictions so that the rest of the challenge was effectively scripted and left no room for the OPFOR to try novel tactics.

One of the generals (of the blue team) is quoted as saying: "You kill me in the first day and I sit there for the next 13 days doing nothing, or you put me back to life and you get 13 more days' worth of experiment out of me. Which is a better way to do it?"

Also:

> The postmortem JFCOM report on MC02 would say "As the exercise progressed, the OPFOR free-play was eventually constrained to the point where the end state was scripted. This scripting ensured a blue team operational victory and established conditions in the exercise for transition operations."
