This Coat of Arms signifies the 13th Field Artillery. A coat of arms is a heraldic emblem associated with units in the US Army. Each regiment and separate table of organization and equipment battalion of the US Army is authorized a coat of arms to be displayed on the organization's flag, called the "colors." This coat of arms usually forms the basis for the unit's distinctive unit insignia, the emblem worn by all members of the unit on their service uniforms. The official mottoes and/or Special Designations are also included in the coat of arms. The 13th Field Artillery's Coat of Arms contains the slogan "Without fear or the hope of reward". A howitzer is displayed at the top of the shield. Captain Hughes labeled this photo as a 1st draft. He did not date it. James C.
