The 12th Coast Artillery Regiment was a Coast Artillery regiment in the United States Army, constituted in the Regular Army on 27 February 1924. It served in the Harbor Defenses of the Chesapeake with headquarters at Fort Monroe, Virginia from 1924 to 1932. At that point, the regiment effectively became the 2nd Coast Artillery; on paper the 2nd Coast Artillery was transferred from the Harbor Defenses of Cristobal in the Panama Canal Zone and the 12th was transferred (less personnel and equipment) to that harbor defense. However, the 12th was never activated again, and on 19 June 1944 was disbanded.^[1]

Distinctive unit insignia

The griffin is a fictitious heraldic animal noted for watchfulness and strength, half eagle and half lion, and emphasizes the motto which translates to "Alert and Courageous."
