42 DIVARTY
U.S. Army
The 42nd Infantry Division Artillery (42 DIVARTY), also known as the "Rainbow" Division Artillery, was activated during World War I as part of the 42nd Infantry Division, one of the first National Guard divisions to serve in France. The unit provided crucial fire support during major campaigns such as the Champagne-Marne, Aisne-Marne, and Meuse-Argonne offensives. Reactivated for World War II, 42 DIVARTY supported the division's advance across France and into Germany, contributing to the liberation of Dachau concentration camp. After periods of inactivation, the unit has continued its legacy as a key artillery command within the Army National Guard, providing mission-ready fire support for domestic and overseas operations.
