The 2nd Battalion, 20th Field Artillery nickamed "Deep Strike," is a United States Army Field Artillery Battalion, currently assigned to Fires Brigade, 4th Infantry Division, and equipped with the M270 Multiple Launch Rocket System.
During the Vietnam War the 2/20th was an Aerial Rocket Artillery battalion, equipped with UH-1 B and C model and AH-1G model helicopters. It was known as "Blue Max." In 1972, the Battalion was relieved from assignment to the 1st Cavalry Division, assigned to the 4th Infantry Division, and activated at Fort Carson, Colorado.
In 1976 the battalion was attached to 8th Infantry Division in Wiesbaden, Germany, where it would remain until it was deactivated in 1984, subsequently reactivated in 1987 and again deactivated in 1992. In September 1998, 9-1 Field Artillery was reflagged as the 2nd Battalion, 20th Field Artillery Battalion. In 2001 the battalion supported the Army’s testing and fielding of the M270A1 launcher and became the first M270A1 MLRS unit in the Army. Soldiers with the 2nd Battalion, 20th Field Artillery Regiment, held a launching ceremony April 17 to present the new MLRS to the 4th Infantry Division. The ceremony consisted of a live-fire exercise attended by key members of the 4th Infantry Division and the 49th Armored Division, Texas National Guard.
In March 2003 the Battalion deployed to Iraq in support of Operation Iraqi Freedom where they performed not only their traditional field artillery tasks, to include firing the Division’s first deep missile fires in combat, but performed armed reconnaissance missions, joint security patrols, cordon and searches, raids, and a wide variety of civil military operations. The Battalion redeployed in March 2004. Returning back to FT Hood the unit under went training equipment maintenance until it was once again called into action in support of Operation Iraqi Freedom in December 2005. Upon the Battalions return from deployment in December 2006 it was increased in size by the addition of a 3rd Firing Battery (Charlie), and adding a radar unit (A/26)and making the 67th FSC which was ad-hoced at the beginning of deployment a permanent part of the Battalion thus increasing the power and potencey of the unit.
The Texas National Guard's 2nd Battalion, 131st Field Artillery Regiment and Delta Battery, 2/20th Field Artillery would round out the 2/20th Field Artillery Battalion in a contingency.
