Focus On U.S. Military Bases In The Middle East

Although most of those are stationed at big bases in Qatar, the United Arab Emirates and Kuwait, many thousands more are scattered around smaller outposts.

Those include troops in Iraq and Jordan, which hosts a small base known as Tower 22 where three U.S. personnel were killed in a drone attack by Iran-backed militia over the weekend. The Pentagon said there have been 165 attacks on U.S. positions in the region since mid-October, according to Bloomberg News.
