As they say, the Romans were still fighting the last war (using the same tactics they had used in the past.) This was their failure. Hannibal came up with a solution to their tactics (which is why you don't want to keep doing the same thing over and over.
Having said that, I don't think we are seeing the Coalition Forces "fighting" the last war. Going in before the Air War started for one.
The United States made a decision to keep the civilian casualties low, we can do this only at a price. I will wait until the war is over to decide if the price was worth it. But, having made that decision, we can not do what we need to do to keep our casualities low (bomb the hell out of everything).
There is more to war then being able to kill, you need organization, command, and supplies. Iraq will fight this war with whatever supplies they have on hand. No matter how much that is, it is not enough.
We are only seeing what the "embedded" reporters are seeing. What is the 82nd Airborne doing, what about the 101st and the 173rd? We are not getting much news from the north, or the west. I have a feeling we have not really seen the "shock and awe" campaign yet.
Anyway, that is my opinion.
Interesting observation.
