 The regimental insignia incorporates specific symbolism in its design.The colors, gold and blue, are the colors of the Chemical Corps, while the tree's trunk is battle scarred, a reference to the historical beginnings of U.S. chemical warfare, battered tree trunks were often the only reference points that chemical mortar teams had across no man's land during World War I.The tree design was taken from the coat of arms of the First Gas Regiment.
