Operation Marne Anvil
Operation Marne Anvil, a month-long operation subordinate to the Corps-level offensive Operation Phantom Strike, was launched by Multi-National Division-Center (MND-C) in October 2007. Marne Anvil followed Operations Marne Husky and Marne Torch II, as part of the Phantom Strike offensive. Unlike previous MND-C operations focused on Sunni extremists and al-Qaeda in Iraq (AQI), the principal targets for Marne Anvil were Shi'a extremists associated with Muqtada as-Sadr’s militia, Jaysh al-Mahdi, located east of Baghdad.
As part of Marne Anvil, the 1-10th Field Artillery battalion established Patrol Base Salie in Nahrawan, a town on the east side of the Diyala river that had been dominated by Shi'a extremists and criminal militias. US forces also targeted the lines of communication used by Sunni and Shi'a extremists for weapons smuggling in this area, degrading their capability to move men and material into the capital. This involved the destruction of a land bridge that crossed the Diyala River, connecting Diyala province with Baghdad.
Like the operations that would come before and after it, Operation Marne Anvil enjoyed support from Concerned Local Citizens groups (now called "Sons of Iraq").
In mid-November 2007, MND-C transitioned to Operation Marne Courageous.
