ShieldThe charges allude to the history of the geographical area to which the organization was allotted originally. The use of the warrior's head and the rattlesnakes was suggested by Orcutt's History, published under the auspices of the Fairfield County (Connecticut) Historical Society. "The first of the Indian Wars in Connecticut was the Pequot War which began in May 1639, in a swamp flat which is now in the village of Southport in the Town of Fairfield. There were at the time in the Housatonic River Valley from Long Island Sound Northward, between two and three thousand Indians. Five plantations were seriously in danger, Stratford, Fairfield, Norwalk, Stamford, and Greenwich. In this year and several following, the actions of the Indians in what is now Fairfield County were such as to awaken great apprehension for the safety of the people." The rattlesnake?harmless when undisturbed but dangerous when provoked?is a symbol associated with the New England patriotism. The blue of the shield represents Infantry.
CrestThe crest is that of the United States Army Reserve.
The coat of arms was originally approved for the 418th Infantry Regiment on 21 April 1925. It was redesignated for the 418th Regiment on 19 February 1960.
