1st Army

The **1st Army** is a designation used by several nations, most notably by the United States, Germany, France, and Russia, often as a primary field army in major conflicts. In the United States, the First Army was established in 1918 during World War I under General John J. Pershing and played a crucial role in the St. Mihiel and Meuse-Argonne offensives. Re-activated for World War II, the US First Army, under General Omar Bradley, led the assault on Omaha and Utah beaches during the D-Day landings and pushed through France and into Germany. In subsequent decades, the First Army's mission shifted to training and preparing reserve and National Guard units, continuing its legacy as a key component of national defense.
