Concept sketch of a military challenge coin. Obverse: A dark, swirling tornado forming over a stylized silhouette of Mount Rainier. The letters 'HHC' are subtly integrated into the base of the tornado. The coin has an antique brass finish. Reverse: The words 'WREAK HAVOC' in large, bold, distressed stencil font, arranged in a slight arc. A faint outline of the JBLM area is visible behind the text. The overall style is rugged and powerful. See more
