The 2nd Battalion of the 43d Coast Artillery Regiment has been consolidated with the 61st Field Artillery Battalion, constituted in 1940, to form the present 61st Field Artillery Battalion. The coat of arms of the 61st Field Artillery Battalion has been amended, by addition of a charge from the coat of arms of the 43d Coast Artillery Regiment, to represent the World War I history inherited by the consolidation. The green oozlefinch was the device on the shoulder sleeve insignia worn by the Railroad Artillery Reserve in France during World War I, of which this regiment was a unit. The motto translates to It Is Good.
The distinctive unit insignia was originally approved for the 61st Field Artillery Battalion on 18 July 1941. It was amended by addition of a charge from the coat of arms of the 43d Coast Artillery Regiment to show World War I history on 7 August 1952. The insignia was rescinded on 6 September 1961.
