The US-led coalition air campaign against ISIS militants in Iraq and Syria has dragged on for months, but the US airmen mounting the raids haven’t lost track of time.

During Christmas Day airstrikes against the terrorist group, some US pilot donned Santa hats, photos of which were shared by the US Air Force, as first spotted by international monitoring group Airwars.

Coalition air forces mounted 18 strikes against ISIS targets in Iraq in Syria on December 25.

Near Raqqa, the group’s de facto capital city in Syria, 11 strikes were directed at ISIS tactical units, fighting positions, vehicles, and weapons, including ISIS’ apparent go-to of late: A vehicle-borne improvised explosive device.

Near Mosul, the second-largest city in Iraq and the terror group’s last stronghold in that country, two strikes were directed at ISIS tactical units, fighting positions, vehicles, weapons, and infrastructure.

According to a release from Operation Inherent Resolve, all aircraft involved in Christmas Day strikes returned to base safely.

The US-led coalition has mounted hundreds of strikes against ISIS in Iraq and Syria, targeting the terror group’s vehicles, weapons, buildings, fighting positions, resources, and tunnel networks.
