I agree. The US units were better trained, equiped and led. They used their advantages as a force multiplier and destroyed units with greater numbers at the point of attack (even though the overall numbers in the general battle favored the US). What the article does show is that
1. The RG just didn't drop their guns and go running back to Baghdad. They had to be defeated. In many cases, killed at their weapons.
2. The US depended on suprise and numbers to aid them. Two things they don't have as much of this time.
I posted this just to prove the point that many of the Iraqis will fight, just as they did last time. We have a better army and we'll win, but to underestimate them is foolish.
