Less well equipped? I’ll take armored vehicles over pickup trucks. And whatever little air support the Iraqis have, is vastly more than ISIS has.
We spent 10x the annual Iraqi military budget to lose 5000 dead. If we had spent the Iraqi military budget, we might have had a lot more situations similar to what happened to that Iraqi armored column. The situations where we did well were when we had the initiative, i.e. conducting raids against insurgents in the small hours of the morning. The ones where we lost most of our men were when they were ambushed with mines and booby traps while on patrol. The Iraqis wandered into one of those situations while advancing pell-mell into Indian country without the benefit of CAS or arty support (tube or MLRS) and paid the price.
