It's nothing new really. Back in the 80's there was this huge combined operations training, consisting of two parts, operation Reforger and operation Sudden strike. The first part was to see how quickly the US could ship it's troops to Europe in case of a Warsaw pact invasion of Western Europe. The second part was to simulate the battle that would follow.
A number of NATO countries were given the role of the 'Bad guys', these included the UK, Germany, and Holland amongst others. Beforehand the agreement had been made that the 'Good guys' were to win the war. However, the baddies stomped all over the goodies, so an order was issued to the baddies that they had to lay off a bit, and they were no longer allowed to use their special forces (British SAS and Dutch SBS were rampaging through the goodies rear areas, causing untold damage by relaying vital information to artillery and aircraft).
Ain't war cool when you know you will win?
One thing though, don't expect too many Iraqis to do suicide runs on US materiel. It ain't their style, most of them are as unhappy with Saddam as the rest of the world. They're just not allowed to admit it.
