US Army Seal
9 line

The implements of warfare, cannon, cannon balls, mortar, powder flasks, pike, and rifle, are all of the type used in the Revolutionary War. Their inclusion in the seal reflects the powers and duties of the revolutionary era Board of War for the procurement and handling of artillery, arms, ammunition, and other war-like stores belonging to the United States. The pike is of the type carried by subordinate officers of infantry. The drum and drumsticks are symbols of public notification, reflecting the tradition of a citizen militia. Drums also served various military purposes in the eighteenth century, such as the regulation of firing in battle by the drummer's beat. The Phrygian cap atop the sword's point is the type of cap given to ancient Roman slaves when they were granted freedom. However, during the French Revolution, the cap was adopted and worn as a "Cap of Liberty,” and is now a traditional symbol of liberty. The coiled rattlesnake and scroll was a symbol that appeared frequently on colonial flags, particularly those representing groups opposed to some aspect of British rule.
