Horseshoer, c. 1918.
This man wears the specialist chevron for a horseshoer, which per regulation was to be worn on both sleeves. It was 2 inches in diameter and supposed to be of olive-drab on olive-drab, but the patch in this photo might be in the dress uniform colors of yellow (dark in this old photography) on dark blue. The service coat for warm climates was of olive-drab cotton, here apparently much faded. The leather and canvas leggings were first issued in 1917. The collar disk is the plain US.
