A military front or battlefront is a contested armed frontier between opposing forces. It can be a local or tactical front, or it can range to a theater. A typical front was the Western Front in France and Belgium in World War I.
The term “home front” has been used to denote conditions in the civilian sector of a country at war, including those involved in the production of matériel.
Both the Soviet and Polish Armies used the term “front” to mean an army group during the Polish-Soviet War and World War II. The equivalent of the term established in the header was the “Theater of military operations”.
