14. Battle of Mosul (2016-2017, U.S. advisory role)
During the Battle of Mosul, U.S. forces shifted to a supporting role, providing critical airstrikes and Special Forces guidance as Iraqi troops fought to reclaim the city from ISIS. Despite this advisory stance, American involvement was pivotal in coordinating urban operations and neutralizing hardened militant positions. The battle left much of Mosul in ruins, underscoring the devastating toll of urban warfare.
