Throughout Petraeus's tenure in Iraq, Multi-National Force-Iraq endeavored to work with the Government of Iraq to carry out this strategy that focuses on securing the population. Doing so required establishing—and maintaining—persistent presence by living among the population, separating reconcilable Iraqis from irreconcilable enemies, relentlessly pursuing the enemy, taking back sanctuaries and then holding areas that have been cleared, and continuing to develop Iraq's security forces and to support local security forces, often called Sons of Iraq, and to integrate them into the Iraqi Army and Police and other employment programs.
