To the old coat of arms of the 112th Infantry Regiment are added a rampant lion as found on the arms of Belgium and the Grand Duchy of Luxembourg grasping a red cross of the province of Lorraine in France. The lion is in the Infantry color and both symbols represent the locale of the Regiment's combat in World War II. The shield is white, the old Infantry color. Service in the Civil War is shown by the cross patée, the badge of the 5th Corps, 3rd Division, in which the organization served in that war. The Spanish castle indicates service in Puerto Rico during the Spanish-American War, while the bridge, which is a representation of the bridge over the Vesle River at Fismes, France, where the Regiment saw its hardest fighting, symbolizes service in the World War I.
The crest is that of the Pennsylvania Army National Guard.
The coat of arms was approved on 2 January 1930. It was amended to show additional war service on 29 August 1951. The insignia was amended to correct the blazon on 16 May 2008.
