• Origins in World War I: The 398th Infantry Regiment, part of the 100th Division, was originally constituted during World War I in 1918, though it was demobilized without seeing combat in that conflict. • World War II Service: The 398th Infantry Regiment was reactivated for World War II as part of the 100th Infantry Division (“Century Division”), seeing extensive combat in the European Theater, including fighting in France and Germany. • Battle Honors: The regiment was involved in key battles such as the Battle of the Vosges, where it fought in the challenging mountainous terrain of eastern France, and contributed to the liberation of Bitche, a heavily fortified town. • Medal of Honor Recipient: Staff Sergeant John F. McGrath of Company A, 398th Infantry, was awarded the Medal of Honor for heroic actions near St. Pravel, France, in November 1944. • Post-WWII Transformation: After WWII, the 398th was inactivated and later reorganized as part of the Army Reserve, with a primary mission of training new soldiers rather than direct combat. • Modern Training Role: Today, Company A, 1st Battalion, 398th Regiment, 2nd Brigade, 100th Division, is part of the Army Reserve’s training structure, focused on training Initial Entry Soldiers and mobilization support. • 100th Division’s Unique Insignia: The division patch features a blue “100” on a white oval with a red border, earning the nickname “Century Division.” • Cold War and Beyond: During the Cold War, the 398th played a vital role in preparing reserve and National Guard units for rapid mobilization, a mission that continues to this day. • Community Engagement: Units of the 398th have a tradition of community involvement, supporting local events, parades, and veteran commemorations across the Midwest. • Legacy of Valor: The 398th’s regimental motto, “I Serve,” reflects its dual legacy of combat heroism during WWII and ongoing commitment to training excellence in the Army Reserve.
