412th Engineer Command (United States). The 412th Theater Engineer Command (412th TEC) is a United States Army Reserve unit that conducts theater-level engineer operations for Eighth U.S. Army, Korea; U.S. Army Europe; and U.S. Army Pacific, supports continental U.S. – based engineer requirements as directed, and is prepared to participate in Joint and Combined regional contingency operations.

History
The 412th Engineer Command provides theater-level engineer support to the Combatant Commander in the event of a contingency operation. It is designed to command hundreds of engineer units and thousands of Soldiers in a war fighting capacity. The Command has historical training relationships in the Pacific and European theaters, and provides direct support to the Eighth US Army in Korea. The Command also is the Army Reserve's Executive Agent for Operation Sand Castle at Fort Irwin, CA, which is a 10-year urban terrain construction mission for engineer units conducting their Annual Training. Prior to mobilization, the 412th ENCOM is under operational control of the Headquarters, U.S. Army Corps of Engineers.

As an operational command, the 412th has 3 brigades and 96 other assigned units with approximately 10,000 Soldiers located throughout the southeast and northeast U.S. These units include the 926th Engineer Brigade, 411th Engineer Brigade, 302d Maneuver Enhancement Brigade, and the 314th Public Affairs Detachment (Press Camp Headquarters).

The Command was formed in the Organized Reserves in 1923, and served in World War II, earning the Meritorious Unit Commendation. In the 1990s, the 412th participated in Operation Joint Endeavor and Operation Joint Forge in Bosnia and Kosovo, and as part of the Hungary Joint Task Force East in several former Warsaw Pact and Soviet countries.
412th Soldiers have assisted with construction missions and supported joint exercises in Thailand, the Philippines, Vietnam, and the Marshall Islands. During the East Timor crisis in 2002, Soldiers from the 412th provided engineer support to the UN.

The 412th headquarters has deployed numerous detachments since the beginning of the Global War on Terror. In 2003, a detachment deployed as the Engineer Section for the Headquarters, U.S. Army Europe. In 2004, the CG and a small detachment supported the Multi-National Force in Baghdad. In 2005, the 412th deployed a design management section to support the 130th Engineer Brigade in Iraq. In 2006 and 2008, the 412th deployed task forces to augment the Gulf Region Division of the Corps of Engineers in Iraq. Currently, more than 800 of its Soldiers have deployed to Iraq. In 2009–2010, DCP 1 deployed to Afghanistan as part of Operation Enduring Freedom. The 412th provided engineering and logistical support for hurricane relief after Hurricane Katrina and Hurricane Rita devastated the Louisiana and Mississippi coasts in the late summer of 2005.
