Shield
Yellow (Or) is used for Armor. The apple charged with the figure "2" is an adaptation of the badge of the old 2d Infantry, New York National Guard, which was known as the "Apple Knockers." The 2d Infantry was the parent unit of the 205th Armor. The sheathed sword (for the Spanish War Medal) represents service during the Spanish-American War; the cactus, service on the Mexican Border; and the fleur-de-lis, service during World War I. The blue color and the wavy partition line stand for the Pacific Ocean; the pointed line protruding beyond the waves represents the mountainous island of Saipan. The crossing of the lines stands for the breakthrough of Japan's perimeter of defense in the Pacific at Saipan and refers to the unit's distinguished participation in that action in World War II.
Crest
The crest is that of the New York Army National Guard.
The coat of arms was approved on 26 March 1968.
