The United States Department of Defense continues to have a large number of temporary military bases in Iraq, most a type of forward operating base (FOB).
Near the end of Occupation of Iraq (2003–2011), the last several camps and forward operating bases were changed to contingency operating bases and sites.
At the height of the occupation the US had 170,000 personnel in uniform stationed in 505 bases throughout all provinces of Iraq.
Control of many U.S.-operated bases was transferred to the Iraqi government during the 2020–2021 U.S. troop withdrawal.
At the request of the Iraqi government in January 2024,[3] and amid rising regional tensions following the 2023 Israeli invasion of Gaza, the US and Iraq are set to begin negotiations to end US military presence in Iraq.
