Given the surprisingly sparse media reports about the supposed deployment of such a large force, Stratfor believes that this information should be taken with a note of caution. The presence of Turkish forces could be a mischaracterization of an expansion of Ankara's footprint in training the National Crowd for Liberating Ninevah rather than an actual deployment of large Turkish units for a mission to retake Mosul. If some element of this report is true, however, this would be a very notable development and a sizable increase in Turkey's commitment to the conflict in Iraq. The addition of three Turkish combat regiments could upend the balance in what has been a largely stagnant front. Iraqi Prime Minister Haider al-Abadi said Dec. 3 that he would reject any foreign ground troops in the fight against the Islamic State, calling any such incursion a violation of sovereignty that would be dealt with accordingly. Iraqi security forces have been working to isolate Islamic State-held Mosul by cutting lines of communication and directing airstrikes by the U.S.-led coalition.
