It was reactivated on 27 October 2006 at Fort Drum, New York under the 20th Engineer Brigade. It deployed to the Iraq War and the Afghanistan War (2001-2021) in 2009. In Iraq, the battalion provided tactical construction in support of United States Division - South, partnered with the Iraqi Army's 10th and 14th Field Engineer Regiments, and enhanced the civil capacity of Iraq via technical support for reconstruction projects.

• Description

A Silver color metal and enamel device 1 inch (2.54 cm) in height overall blazoned: Sable, an anchor debruised by two oars saltirewise between in fess two increscents all Argent; on a chief of the last embattled a cross Gules.

• Symbolism

Black and white were the old colors of the Engineer Corps. The anchor and oars device was the badge of the Engineers and Pontoniers of the Army of the Potomac where the old units of the regiment did such gallant service. The crescents are the device of General Winfield Scott and represent the service of the old company in 1846–1848 in the Mexican War. In France, the regiment served with great gallantry in the 5th Division. The crossing of the Meuse near Dun is indicated by the device in chief of the shield which is not only a cross for the crossing of the river but the device of the lords of Dun.

• Background

The distinctive unit insignia was originally approved for the 7th Engineer Regiment on 27 August 1926. It was redesignated for the 7th Engineer Battalion on 7 March 1940. It was redesignated for the 7th Engineer Combat Battalion on 13 May 1940. The insignia was redesignated for the 7th Engineer Battalion on 6 July 1954.
