2004. The 116th Rear Area Operations Center moved to FOB Endurance after Thanksgiving 2004 from Mosul AB. Tiger Squadron of the 3rd Cavalry Regiment was the major US combat unit on FOB Q-West during October 2007 - February 2009. The unit oversaw and supported combat operations conducted out of multiple subunit locations in the region. ISIL occupation Qayyarah Airfield West came under ISIL occupation in 2014 along with the Mosul area. During the occupation, the base had been the target of airstrikes by aircraft of the international coalition. In February 2015, there were reports that ISIL evacuated the base intermittently in the aftermath of coalition bombing attacks. "Dozens of dead and wounded" among the ISIL militants in the attacks were also reported. Post-ISIL period On 9 July 2016, the Iraqi army recaptured Qayyarah Airfield West from ISIL during the Mosul offensive, reportedly "without any resistance". The airfield was considered a "strategic launch-pad" for the ongoing offensive. Photos showed obviously unusable Iraqi MiG-23/MiG-27 fighter/attack aircraft. Q-West then served as the international headquarters for the Battle of Mosul, beginning on 16 October 2016. About 560 U.S. troops from the 101st Airborne Division were deployed here for the battle. Deployments included command and control elements, a security detachment, an airfield operations team, and logistics and communications specialists. Also a life support area for the Iraqi forces was set up by the U.S. troops. On 22 October, the repaired airfield and its runway were reopened, with the first of many fixed-wing cargo airplanes arriving at the airfield. On 30 October, an Iraqi Air Force C-130J Super Hercules landed at Qayyarah West Airfield, the first time a fixed-wing aircraft from the Iraqi security forces landed there since the airfield was recaptured from ISIL. The United States Army left the site on May 13, 2020. Units Company A, 39th Brigade Engineer Battalion, Task Force Strike. Company G, 526th Brigade Support Battalion, Task Force Strike.
