Authorised 17 June 1937
A Gold color metal and enamel device 1 5/32 inches (2.94 cm) in height overall consisting of a shield blazoned: Gules, a lion dormant Or. Attached below the shield a Gold scroll inscribed "SERVABO FIDEM" in Black letters.
The colors red and yellow identify the organization as Artillery. The lion, though depicted asleep, is said to sleep with its eyes open (though they may appear shut) and is thus "ever on guard" and ready for any emergency and action.
The distinctive unit insignia was originally approved for the 33d Field Artillery Regiment on 17 June 1937. It was redesignated for the 33d Field Artillery Battalion on 3 January 1941. It was redesignated for the 33d Artillery Regiment on 11 April 1958. The insignia was redesignated effective 1 September 1971 for the 33d Field Artillery Regiment and amended to change the symbolism of the design. Coat of Arms
