Per fess embattled Or and Gules, a key Sable, wards upward and outward and a lightning bolt Tenné in saltire, overall and throughout, a bayonet erect of the first; on a chief Azure (Dark Blue) a stylized image of an oxen drawn covered wagon of the first.
That for the regiments and separate battalions of the Oregon Army National Guard: From a wreath Or and Gules, a demi-disc of the like charged with the setting sun with twelve light rays Or (the shoulder sleeve insignia of the 41st Division), behind a beaver sejant Proper.
WE WILL PREVAIL.
The following elements form the Special Troops Battalion, the original unit designation, and provided support to the 41st Infantry Brigade Combat Team: the lightning bolt alludes to the signal network support; the key denotes the safekeeping of military intelligence provided; and the embattled fess suggests engineering capabilities. The bayonet, which attaches to the M1 Garand rifle, symbolizes the unit's close combat mission, also honoring the lineage of the 41st Infantry Division, the first American Division to deploy and the longest to remain overseas during World War II. The chief with the image of the oxen drawn covered wagon pays tribute to the pioneers, whose descendents comprise the unit.
The crest is that of the Oregon Army National Guard.
The coat of arms was originally approved for the Special Troops Battalion, 41st Infantry Brigade Combat Team on 1 February 2008. It was redesignated for the 741st Engineer Battalion with the blazon and symbolism updated effective 1 October 2015.
