On September 30 local time, the U.S. Department of Defense issued a statement saying it would reduce the size of U.S. troops in Iraq. Reuters quoted a U.S. official as saying that as of early 2025, the number of U.S. troops in Iraq was about 2500. Previously, its main task was to combat extremist organizations. Once the transition is complete, the number of U.S. troops in Iraq will drop to less than 2000, most of which are stationed in Erbil. At the same time, the U.S. military in Iraq will focus on normal bilateral security cooperation rather than attacking extremist groups.
