Silver
Silver is a chemical element with symbol Ag (from the Latin "", derived from the Proto-Indo-European "h₂erǵ": "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

Symbolism: Shield: The shield is red for Artillery. The saltire is taken from the State flag of Alabama, the birthplace of the Regiment. The winged spur signifies that the unit was mounted. Crest: The two Distinguished Unit Citations awarded the organization during World War II are symbolized by the crescent for French Tunisia and the raguly chevron for the bridgehead at Remagen. The irregular upper edge of the chevron alludes to the attempted destruction of the Ludendorff Bridge by the retreating enemy. The fountain is used to represent the organization's action along the Meuse River; and the fleur-de-lis symbolizes the unit's action in the Ardennes.
