English: From en.Wikipedia: The Chemical Corps regimental insignia was approved on 2 May 1986. The insignia consists of a 1.2 inch shield of gold and blue emblazoned with a dragon and a tree. The shield is enclosed on three sides by a blue ribbon with Elementis Regamus Proelium written around it in gold lettering. The phrase translates to: "Let us (or we) rule the battle by means of the elements". 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 Chemical Regiment. The dragon symbolizes the fire and destruction of chemical warfare. See: Chemical Corps
