Taking Tal Afar

[Political]
The Washington Post has an account of the counter-insurgency operations of the 3rd Armored Cavalry Regiment in taking Tal Afar.

U.S. military experts conducting an internal review of the three dozen major U.S. brigades, battalions and similar units operating in Iraq in 2005 privately concluded that of all those units, the 3rd Armored Cavalry Regiment performed the best at counterinsurgency, according to a source familiar with the review's findings.

"Every time you treat an Iraqi disrespectfully, you are working for the enemy," McMaster said he told every soldier in his command.

One out of every 10 soldiers received a three-week course in conversational Arabic, so that each small unit would have someone capable of basic exchanges with Iraqis. McMaster, who holds a PhD in history from the University of North Carolina and is an expert on the Vietnam War, distributed a lengthy reading list to his officers that included studies of Arab and Iraqi history and most of the classic texts on counterinsurgency. He also quietly relieved one battalion commander who didn't seem to understand that such changes were necessary.

Instead of staging a major raid into the city for suspects and then moving back to operating bases, McMaster said he took a sharply different tack, spending months making preparatory moves before attacking the entrenched insurgents in Tall Afar. That indirect approach demonstrated tactical patience, a key to effectively battling an insurgency and a skill that doesn't come easily to the U.S. military.
