"On 12 November 2005, Coalition and Iraqi forces demonstrated again the flexibility and agility so necessary for counterinsurgency (COIN) operations against a smart, adaptive foe. After concentrating large-scale operations for months in Ninewah and Al Anbar Provinces northwest and west of Baghdad, Coalition forces conducted a new, no-notice operation in Diyala Province, northeast of Baghdad. Named Operation Knockout, this successful action reinforced the tactics, techniques, and procedures needed to defeat the insurgents and terrorists in Iraq."
