The review grew out of the OIG inspection of Embassy Baghdad in February/March 2009 but included personnel who had served in Afghanistan, Pakistan, Saudi Arabia, Lebanon, Sudan, Yemen, Chad, and other high-stress posts. It was based in part on a survey of about 1,200 Foreign Service and Civil Service personnel who had served in these posts since September 2007. Approximately 400 officers replied (75 percent of the respondents had served in Iraq, Afghanistan, or Pakistan).
