I would shift Iraqi units to the bordwe of Anbar and Syria (the Shia ones), I would send the Kurdish unit to the southern border opposite the Iraninan border.
Unfortunately, it's this exact force deployment process that has led to high desertion/AWOL rates, and the lack of true combat power. At any given time in month, a third of my TF's Plt (+) of Shewanis (pure Shi'a) wanted to be on leave (for 10 days). It was next to impossible to muster enough forces.
