The New Iraqi Army is doing just that:
Iraqis may differ on whether U.S. troops should be in the country, but all agree that the Americans are formidable warriors. Increasingly, Iraqi troops are wearing similar combat uniforms and driving hummers. The Iraqi soldiers consciously copy their U.S. counterparts. This includes handling their weapons, and moving around, in a similar fashion. But it isn’t all superficial imitation, the Iraqis stand and fight now. U.S. troops, back in Iraq after having been away for a year or so, are pleasantly surprised to find, when called to reinforce an Iraqi unit (like a checkpoint, or a police station) under fire, that the Iraqis are now fighting harder and smarter. In the past, the U.S. troops would often show up to find the Iraqi troops or police had fled.
Given that it takes a couple years to turn out a world-class NCO, it looks like the Iraqis are making great progress.
