103rd Military Intelligence Battalion
"Top of the Rock"
In 2004 the 3rd Infantry Division began transformation to the US Army's new modular force structure. As a result various habitually attached Division level support units was inactivated and their elements reactivated as part of reorganized and redesignated units with the Division and its line brigades. As a result, the 103rd Military Intelligence Battalion was deactivated in early 2004. Some of its companies were reflagged a the integral military intelligence elements of the Brigade and Division Special Troops Battalions.
The mission of the 103rd Military Intelligence Battalion was to deploy rapidly to a contingency area by air, land, and sea to conduct Intelligence and Electronic Warfare (IEW) operations worldwide. The unit had 3 line Military Intelligence Companies detailed to support 3rd Infantry Division's 3 line Brigades. For instance, C Company habitually assigned to the 3rd Brigade.
Although the 103rd Military Intelligence Battalion was only formed under that name in 1981, its lineage can be traced back to World War II. The Battalion takes it's lineage from the 851st Army Security Agency Company and 3rd Military Intelligence Company, both of which merged to form the 103rd Military Intelligence Battalion on 16 September 1981. The Battalion was originally located in Germany and in the summer of 1996, relocated to Fort Stewart, Georgia.
The 851st Army Security Agency Company was originally formed as the 3377th Signal Service Detachment. The 3377th was activated in January 1945 on Luzon in the Philippines. The unit was reorganized several times until in October 1951, when it was redesignated the 851st Communications Reconnaissance Detachment. The 851st CRD participated in 4 Korean campaigns, including the first UN counteroffensive. The detachment was deactivated in Japan in August 1956. That same year it was briefly reactivated as the 851st Army Security Agency Detachment. It was finally designated the 851st Army Security Agency Company and reactivated in July 1974. With the consitution of the 103rd Military Intelligence Battalion, it was concurrently reorganized and redesignated as Company A, 103rd Military Intelligence Battalion.
The 3rd Military Intelligence Company was activated in France in September 1944 as the 3rd Counterintelligence Corps. It was inactivated 2 years later after having participated in 4 World War II campaigns, including Rhineland and Ardennes-Alsace. In 1949, the detachment was reactivated and served in the Korean War. It participated in 8 campaigns including the Chinese Communist Force Intervention and the second and third Korean Winters. During January 1958, the detachment was reorganized and redesignated as the 3rd Military Intelligence detachment and attached to the 3rd Infantry Division. The detachment was assigned to the 3rd Infantry Division in April 1974. With the consitution of the 103rd Military Intelligence Battalion, it was concurrently reorganized and redesignated as Company B, 103rd Military Intelligence Battalion.
In April 1996, the Battalion unfurled its colors at its new home at Fort Stewart, Georgia, beginning a new era in support of the soldiers of the Marne Division. In September 2000, the Battalion colors were moved to Tuzla, Bosnia-Herzegovinia as Task Force Dagger for Stabilization Force (SFOR) 8 and 9, where they provided intelligence support to the Multinational Division (North) commander. The Battalion returned to Fort Stewart in October 2001.
Elements of the 103rd Military Intelligence Battalion deployed in 2003 as part of Operation Iraqi Freedom in support of the 3rd Infantry Division (Mechanized). They returned in late 2003. Soldiers from Company C, 103rd Military Intelligence Battalion, under the operational control of 3rd Brigade, used the knowledge they gained during their deployment to Iraq to improve their training during exercises at Fort Benning, Georgia in late 2003..
In 2004, with the transformation of the 3rd Infantry Division to the US Army's new modular force structure, the 103rd Military Intelligence Battalion was inactivated, with elements reflagged as the organic military intelligence components of the new Division and Brigade Special Troops Battalion.
