The strategy underpinning the "surge" of forces, as well as the ideas Petraeus included in US army Field Manual 3–24, "Counterinsurgency", have been referred to by some journalists and politicians as the "Petraeus Doctrine", although the surge itself was proposed a few months before Petraeus took command. Despite the misgivings of most Democratic and a few Republican senators over the proposed implementation of the "Petraeus Doctrine" in Iraq, specifically regarding the troop surge, Petraeus was unanimously confirmed as a four-star general and MNF-I commander on January 27.
