Army group
From Academic Kids
An army-group is a military organization (formation) consisting of several armies, and is supposed to be self-sufficient for indefinite periods. An army group is usually responsible for a particular geographic area. The term was used in Germany, the United Kingdom, and the United States. In the Soviet Union an army group was called a "front".
Formations at the level of army or army group should not be confused with a national army, the land forces of a country. A hypothetical example: The Free Country Army could be composed of the First, Third, and Ninth armies.
Army groups may be multi-national formations. For example in 1944–45 during the Second World War, Montgomery's 21st Army Group comprised the British Second Army, Canadian First Army, and US Ninth Army.
