Does Jay Garner have an official title?

News reports I’ve seen describe Jay Garner’s role in Iraq, but he doesn’t seem to have an official title in that capacity:

So, does Gen. Garner have an official title in his job as the interim administrator of Iraq? Or is this an area that’s so diplomatically tricky the U.S. has decided it’s better not to give him a title but just a job description?

Historically and geographically, I suppose “Satrap” would be appropriate, but I hardly think the U.S. would award that title to one of its officials…

General Garner is the Director, Office of Reconstruction and Humanitarian Assistance for Post-war Iraq.
