to the continuing violence in Iraq and the growing influence of non-state organizations, such as the Islamic State of Iraq and the Levant, the United States would be elevating its security commitment in the region. Approximately 800 U.S. troops secured American installations like the Embassy in Baghdad and the Consulate in Erbil as well as taking control of strategic locations like the Baghdad airport in cooperation with Iraqi troops. U.S. forces also undertook a mission to "assess and to advise [Iraqi security forces] as they confront [ISIL] and the complex security situation on the ground." Reports from these American units about the capabilities of the Iraqi military have been consistently grim, viewing them as "compromised" by sectarian interests. On 13 August 2014, the U.S. deployed another 130 military advisers to Northern Iraq and up to 20 U.S. Marines and special forces servicemen landed on Mount Sinjar from V-22 aircraft to coordinate the evacuation of Yazidi refugees joining British SAS already in the area.

By early December 2014, the number of U.S. ground troops in Iraq had increased to 3,100.

However, it limits military force to three years, requires the administration to report to Congress every 60 days, and prohibits the deployment of U.S. combat troops, except in specific cases, such as those involving the rescue or protection of U.S. soldiers, or for intelligence operations. During the early morning hours of 14 December 2014, U.S. ground forces allegedly clashed with ISIL alongside the Iraqi Army and Tribal Forces near the Ain al-Assad Airbase, west of Anbar, in an attempt to repel them from the base of which includes about 100 U.S. advisers in it, when ISIL attempted to overrun the base.
