I have been working on an iraqi OOB too, although incorporating fictional alternate history units (let's put it that way) alongside the real ones while still ensuring that the AI still picks insurgents only if played against the americans post OIF (so that you do not have to switch OOBs all the time).May I ask what sources are you using so we can exchange info?
One of mine is a PDF file which can be found here under "Register of the transfers of major conventional weapons to Iraq 1970-2004":
