NOUS SERVONS (We Serve).
Red and white are the colors of the Engineer Corps. The windmill, taken from the former seal of the City of New York, represents the territory in which the regiment was organized; the wheel alludes to the service of the regiment in the Transportation Corps. The fleur-de-lis symbolizes World War I service.
The crescent, which appears on the flags of Algeria and of Tunisia, has long been a symbol of North Africa. It commemorates the Battalion's assault landing during World War II while participating in the Algeria-French Morocco campaign and action in the Tunisia campaign. The crowned eagle appears on the coat of arms of Palermo, capital of Sicily; it refers to the unit's war service during the action in that area. The four arms of the cross, taken from the coat of arms of Rome, capital of Italy, stands for the Battalion's participation in four campaigns through Italy from Naples to the North Apennines.
The coat of arms was originally approved for the 39th Engineer Regiment on 17 June 1937. It was redesignated for the 19th Engineer Regiment (Combat) on 19 September 1940. The insignia was redesignated for the 52d Armored Engineer Battalion on 4 September 1952. The coat of arms was redesignated and amended to add a crest for the 52d Engineer Battalion on 30 July 1968.
