The 38th Field Artillery Regiment Distinctive Unit Insignia, often referred to as a “unit crest” or simply a DUI for short, was first approved for the 38th Field Artillery Battalion on 8 July 1941 along with a unit motto, “Steel Behind The Rock.’ It was redesignated to reflect the unit’s changing status, first as the 38th Artillery Regiment in 1958 and then as the 38th Field Artillery in 1971. Its shield is red, the branch color of Artillery. A combination of three pallets and eight artillery shells denotes the numerical designation of the unit. The crest of the insignia contains Mt. Rainier, emblematic of Washington State where the Regiment was originally formed, and a star that stands for Texas, the location of Fort Sam Houston where the unit was organized and redesignated before World War II.
Assigned to the 2nd Infantry Division during both World War II and the Korean War, the Regiment would participate in five campaigns during World War II and ten during the Korean War. During the Second World War, the Regiment was the recipient of the Belgian Fourragere 1940 with two citations in the Order of the Day of the Belgian Army, while its service in Korea was honored with a Presidential Unit Citation and two Republic of Korea Presidential Unit Citations.
As of 2023, the 1st Battalion, 38th Field Artillery Regiment is serving in the 210th Field Artillery Brigade in Korea.
