The European Theater of Operations, United States Army (ETOUSA) was a theater of Operations responsible for directing United States Army operations throughout the European theatre of World War II, from 1942 to 1945.

It was the last United States field army to see service in northwestern Europe during the war and was commanded by General George S. Patton until his death in December 1945. The Fifteenth Army served two separate missions while assigned to the area. During the later stages of the war its mission was the training and rehabilitation of units and acting as a defensive line against counterattacks. After World War II its mission was to carry out occupation duties and to gather historical information related to the European Theater of Operations. Fifteenth Army was inactivated at Bad Nauheim, Germany, in 1946.
The Twelfth United States Army Group was the largest and most powerful United States Army formation ever to take to the field, commanding four field armies at its peak in 1945: First United States Army, Third United States Army, Ninth United States Army, and Fifteenth United States Army. The order of battle across the four armies comprised 12 corps, containing a total of 48 divisions. Formed eight days after the Normandy landings, it initially controlled the First and the Third US Armies. Through various configurations in 1944 and 1945, the Twelfth US Army Group controlled the majority of American forces on the Western Front. It was commanded by General Omar Bradley with its headquarters established in London on 14 July 1944.
The VI Corps was activated as VI Army Corps in August 1918 at Neufchâteau, France, serving in the Lorraine Campaign.

It was formed when 6th AG liberated southern and northern Alsace and adjacent eastern Lorraine, but could not clear central Alsace. During Operation Nordwind in December 1944, the 19th Army attacked north out of the Pocket in support of other German forces attacking south from the Saar into northern Alsace.

The Western Allied invasion of Germany was coordinated by the Western Allies during the final months of hostilities in the European theatre of World War II. In preparation for the Allied invasion of Germany east of the Rhine, a series of offensive operations were designed to seize and capture its east and west banks: Operation Veritable and Operation Grenade in February 1945, and Operation Lumberjack and Operation Undertone in March 1945; these are considered separate from the main invasion operation. The Allied invasion of Germany east of the Rhine started with the Western Allies crossing the river on 22 March 1945 before fanning out and overrunning all of western Germany from the Baltic in the north to the Alpine passes in the south, where they linked up with troops of the U.S. Fifth Army in Italy. Combined with the capture of Berchtesgaden, any hope of Nazi leadership continuing to wage war from a so-called "national redoubt" or escape through the Alps was crushed, shortly followed by unconditional German surrender on 8 May 1945. This is known as the Central Europe Campaign in United States military histories.
The 1st Army Corps was first formed before World War I. During World War II it fought in the Campaign for France in 1940, on the Mediterranean islands of Corsica and Elba in 1943 - 1944 and in the campaigns to liberate France in 1944 and invade Germany in 1945.

En route to the Brenner Pass it overran eleven concentration camps at Landsberg, Germany.
The Seventh Army was a United States army created during World War II that evolved into the United States Army Europe (USAREUR) during the 1950s and 1960s.

Major General Carlos Brewer was a United States Army officer who commanded the 12th Armored Division during World War II. After training the 12th Armored Division, he was not permitted to command the division in combat due to his age, so he requested his rank be reverted from major general to Colonel so that he could become an artillery officer in the European Theater of Operations (ETO). He innovated the method of field artillery targeting used in World War II, and implemented triangular organization of divisions.
