Three Block War: Vigilant Resolve is an excerpt of the full-length Three Block War. Vigilant Resolve recounts the action of Marines in the first Fallujah battle of April 2004 against Iraqi mujahideen. Marine units included 2nd Battalion, 1st Marines, which battled insurgents in 'The Jolan,' a congested northwestern Fallujah neighborhood where the 2/1 engaged in vicious urban combat.
In the southeast, 1st Battalion, 5th Marines advanced from an industrial zone into Fallujah's urban battle template; which included IEDs, ambushes, indirect fire, and snipers firing from the towering minarets of mosques. One-Five and Two-one's main assault was reinforced by 'Darkside,' 3rd Battalion, 4th Marines; and supported by units such as Bravo Company, 1st Reconnaissance Battalion, which endured a brutal ambush in rural farmland south of Fallujah.
