Activation through World War II in February 1943 to May 1946
The 555th Engineer Brigade was constituted in the United States Army on 1 February, 1943 as Headquarters and Headquarters Company, 1103d Engineer Combat Group. On 25 February, 1943, the unit was activated at Fort Devens, Massachusetts.
While assigned to the First Army, the 1103d crossed the English Channel during the period of 20 to 22 June, 1944. The 1103d earned it first of five campaign streamers during the Normandy Invasion, clearing and maintaining supply routes at Omaha and Utah Beaches. After a successful landing, the unit executed mine clearing, road building and road maintenance operations.
In August 1944, the 1103d was transferred to General George S. Patton’s Third Army. Throughout the fall of 1944, the 1103d protected captured bridges on the Loire River, bridged the Moselle River, and breached massive forts at Metz for the assaulting forces. During these engagements, the 1103d earned two additional campaign streamers for the Northern France and Ardennes-Alsace Campaigns.
In late February, 1945, the 1103d was called to support Ninth Army in the Ruhr Cleanup. Here, they earned a fourth streamer in support of the Central European Campaign. The unit then proceeded to the Rhineland with XVI Corps. They remained with XVI Corps for the remainder of the war, earning a fifth streamer in support of the Rhineland Campaign.
The 1103d was inactivated on May 8, 1946 in Germany.
Post World War II in Germany in January 1947 to June 1969
Between 1947 and 1969, the unit served at Russelheim, Kaufbeuren, Ettlingen, and Karlsruhe, Germany as part of the defense of western Europe during the Cold War. During this period it was reorganized and redesignated multiple times.
On 20 January, 1947, the 1103d was activated at Russelheim, Germany. On 5 March, 1947, the 1103d was redesignated as Headquarters and Headquarters Detachment, 555th Composite Service Group. Two years later, on 7 March 1949, it was redesignated and reorganized as Headquarters and Headquarters Company, 555th Engineer Combat Group. Finally, on 1 April, 1953, the 555th Engineer Combat Group was reorganized and redesignated as Headquarters and Headquarters Company, 555th Engineer Group.
During this period the 555th was responsible for providing engineer support to 7th Army, including obstacle construction, route maintenance, and tactical bridging. In addition, they were responsible for operating and maintaining several critical military bridges across the Rhine.
On 25 June, 1969, the 555th was inactivated. Soldiers of the 555th joined Soldiers of the 540th Engineer Group to form the 7th Engineer Brigade, VII Corps.
Activation at Fort Lewis, Washington to Operation Iraqi Freedom (January 1992 to April 2003
On 18 January, 1992, the 555th Engineer Group was activated at Fort Lewis, Washington.
The 864th Engineer Battalion (Combat Heavy) and the 73rd Engineer Company (Assault Ribbon Bridge) were the first units assigned to the 555th on 16 November 1991. The 87th Engineer Detachment (Fire Fighters) and the 54th Engineer Detachment (Topographic) were assigned on 16 January 1992. The 14th Combat Engineer Battalion (Corps) (Wheeled) moved from Fort Ord, California to Fort Lewis upon closure of Fort Ord and joined the group on 16 October 1993.
The unit conducted rigorous training both in the field and at the Fort Lewis Simulation Center during the decade following its activation in Washington. Other notable missions included a short-notice deployment to Yakima in 1997 to fight fires, and training evaluations for Army reserve units from states including South Dakota and Utah.
The 864th Engineer Battalion deployed several times in support of construction missions throughout this period. The missions included a deployment to Exercise Cobra Gold in Thailand, and two deployments to Texas to build roads along the Mexican border in support of Joint Task Force 6.
The 555th also participated in numerous construction projects on and around Fort Lewis, Washington. These projects included road repair and road upgrades, culvert installation, and construction of bridges and demolition bunkers.
Operation Iraqi Freedom in April 2003 to September 2009
In January 2003, the 555th Engineer Group received orders to deploy with the 4th Infantry Division (Mechanized) as a member of Task Force Ironhorse to the CENTCOM Area of Responsibility. From April 2003 to March 2004, the 555th deployed in support of Operation Iraqi Freedom Phase I (Liberation of Iraq) and Phase II (Transition of Iraq). Moving into Iraq in late April, the Group established its Headquarters at Forward Operating Base Speicher, in Tikrit, Iraq. Attached units included the 5th Combat Engineer Battalion (Corps) (Mechanized), the 14th Combat Engineer Battalion (Corps) (Wheeled), the 223d Engineer Battalion (Combat) (Heavy), the 565th Combat Engineer Battalion (Provisional), the 229th Construction Support Equipment Company, the 285th Construction Support Equipment Company, and the 463d Firefighting Detachment. During its tour the Group provided assured mobility, force protection and sustainment engineer operations to all brigades in Task Force Ironhorse.
Upon returning from deployment, the 555th Engineer Group was provisionally redesignated by U.S. Army Forces Command (FORSCOM) as the 555th Combat Support Brigade (Maneuver Enhancement) [CSB (ME)] at Fort Lewis, Washington on 4 October 2004.
From October 2005 through September 2006, the 555th CSB (ME) deployed again in support of Operation Iraqi Freedom Phase III (Iraqi Governance) and Phase IV (National Resolution). As the Divisional Engineer Brigade attached to the 101st Airborne Division (Air Assault) in Multinational Division North (MND-N), the unit was headquartered at Tikrit, Iraq. The MND-N area of operation included most of northern Iraq from just north of Taji to the Turkish Border. The major units attached to the 555th during this deployment were the 14th Combat Engineer Battalion (CEB) and the 505th Engineer Combat Battalion (Heavy) (North Carolina Army National Guard). The 557th Expeditionary RED HORSE (USAF) was under the Brigade’s Tactical Control (TACON). The principal missions of the 555th were construction, assured mobility (route clearance), coalition munitions clearance, and Iraqi Army Engineer partnership.
Nine months after returning from its second tour in Iraq, on 16 June 2007, the 555th CSB (ME) was reorganized and redesignated as Headquarters and Headquarters Company, 555th Engineer Brigade at Fort Lewis, Washington.
From September 2008 through September 2009, the 555th Engineer Brigade deployed for its third tour to Iraq. They participated in Operation Iraqi Freedom Phase V (Iraqi Surge) and Phase VI (Iraqi Sovereignty) as the Multi-National Corps-Iraq Theater Engineer Brigade. Operating out of Joint Base Balad, the Brigade initially supported the XVIII Airborne Corps, and later I Corps. They orchestrated full spectrum engineer operations for over 3000 Army, Air Force and Navy Engineers. In partnership with Iraqi Army Engineers, the unit maintained assured mobility, conducted tactical construction, increased Iraqi Army capabilities, and enhanced civil capacity development in support of coalition forces and Provincial Reconstruction Teams (PRTs). Three multifunctional Army engineer battalions (the 5th, 14th, and 54th), the 557th RED HORSE, and numerous Air Force and Navy Engineer Detachments rounded out the Triple Nickel Team.
In September 2009, the 555th Engineer Brigade returned to Fort Lewis (now Joint Base Lewis-McChord) to reset and prepare for future operations in support of the Global War on Terror.
555th Engineer Brigade was designated as a subordinate unit of reactivated 7th Infantry Division, 01 October 2012
Operation Enduring Freedom, "Joint Task Force Triple Nickel" in 2013
Starting January 2013, the brigade headquarters deployed for nine months to Afghanistan as "Joint Task Force (JTF) Triple Nickel" to assume command of the U.S. Theater Engineer Brigade in support of the International Security Assistance Force. The 555th Engineer Brigade became the lead element in a 5,000-strong joint team composed of U.S. Army, Navy, and Air Force engineer units, including elements of the Regular Army, National Guard, and Reserves. JTF Triple Nickel's mission included a critical triad of engineering needs, including training Afghan National Army engineer units, construction and deconstruction projects, and removal of enemy roadside bombs along key roadways.
With coalition mentorship, including training and support from JTF Triple Nickel, more than 40 ANA engineer companies now operate independently, including route clearance units, and five construction battalions have also been established. These construction units have already built and improved Afghan roads and facilities throughout the country, helping ensure that
Afghan forces can build, protect, and sustain their own infrastructure, especially after the drawdown of coalition forces. The 555th managed more than 240 construction projects, totaling more than $40 million in value, to support the draw down and consolidation of coalition forces. The brigade also established and managed small-repair teams which completed well over 100 health and safety-related projects (such as plumbing and electrical fixes) for smaller bases across Afghanistan, helping fill the gap in essential services as contractors draw down. JTF Triple Nickel's ongoing route clearance mission led to the discovery and safe removal of over 300 enemy-emplaced improvised explosive devices from key roadways across the theater, thanks to the continued efforts of more than 30 route clearance patrols operating under the brigade. This has helped protect the lives of both Coalition forces and the Afghan populace, both targeted by IEDs.
