Shield
Silver gray and golden yellow are the colors traditionally used by the Finance Corps; black represents solidity and solvency. The embattlement suggests the canyon terrain of Arizona, the unit's home state, nicknamed "Grand Canyon State." The gold disk, alluding to the sun, also recalls coinage, monetary exchange and finance. The crossed key and sword represent teamwork and cooperation; the key symbolizes control of funds and security and the sword is for military preparedness.
