Operation Inherent Resolve
Since 2014, the United States, United Kingdom, and a coalition of other nations have supported the efforts of local allies to defeat ISIS in Iraq, Syria, and Libya. In 2023, the Unit was called up to support the Operation by assuming command and control over several support bases in Iraq, Syria, and Kuwait.[3][6] In this role, the unit provided logistical and security coordination for coalition forces.[7]
The unit returned to the United States in 2024.
