U.S. Army Reserve



With much of the Army’s engineering capability in the Army Reserve, the ability of the 412th Theater Engineer Commands to respond rapidly, sometimes within 24 hours, is vital to success of the Total Force as it provides theater-level engineer support to combatant commander during contingency operations. The 412th TEC maintains mission command of engineering forces at the theater level as a deployable command post, with three brigades and 96 assigned units throughout the eastern United States.

The engineering expertise in the more than 12,000 Soldier force includes survey and design, building, road and bridge construction, road repairs, and upgrades to physical facilities.

The command has historical training relationships in the Pacific and European theaters and provides direct support to Eighth Army in Korea. It has deployed numerous detachments since 9/11, supporting Multi-National Force-Iraq, and augmenting the Gulf Region Division of the U.S. Army Corps of Engineers in Iraq.

In 2009, Deployable Command Post 1 deployed to Afghanistan as part of Operation Enduring Freedom. In addition to supporting military operations overseas, it also provided engineering and logistical support domestically following natural disasters such as Hurricanes Katrina and Rita, which devastated the Gulf Coast in 2005.

Its lineage dates back to July 1923 when it was constituted in the Organized Reserve as the 372nd Engineer Regiment. It was ordered into active military service at Camp Claiborne, Louisiana, and departed the U.S., arriving in England, August 21, 1943.

The regiment was engaged in the Central Europe Campaign until May 1945 and was awarded the Meritorious Unit Citation for World War II.
