378th Infantry Regiment (United States)
The 378th Infantry Regiment is a unit of the United States Army with a long history in both World Wars and the Army Reserve. It was first formed in 1918 for World War I but did not deploy before the armistice. The regiment was reconstituted in the Organized Reserve in 1921 and trained in Oklahoma. During World War II, it served as part of the 95th Division, trained in the United States, and then fought in Europe from 1944 to 1945, taking part in campaigns from Normandy to Central Europe. The regiment was inactivated in 1945 after the war.
In 1947 the 378th Infantry was reactivated in the Organized Reserves and has since served as part of the United States Army Reserve. It underwent several reorganizations and changes in assignment, mainly within the 95th Division (Training) and related commands, with battalions stationed in Oklahoma and elsewhere. After the September 11, 2001 attacks, units of the 378th were called to active duty for the global war on terrorism. Between 2007 and 2009 the regiment shifted under different training divisions, and today its battalions remain part of Army Reserve training commands.
