Mujahideen Shura Council Operation Swarmer was a joint U.S-Iraqi air assault offensive targeting insurgents in Salahuddin province, near the central city of Samarra, Iraq.

Samarra was the site of the bombing of the revered Al-Askari Shiite Shrine on 22 February 2006, that set off a wave of sectarian killing that claimed almost 500 lives.

Coalition forces said they had captured a number of weapons caches containing shells, explosives and military uniforms.

Iraqi Foreign Minister Hoshyar Zebari stated that insurgents were "trying to create another Fallujah".

Bennett points out that the military term air assault refers specifically to moving troops into an area.
