 A bomber offensive is sometimes also known as a strategic bombing offensive and was prominently used by the Allies on a large scale during World War II.Use of ground attack aircraft in support of ground offensives can be said to be an air offensive, such as that performed in the opening phase of the Red Army's Operation Kutuzov and Operation Polkovodets Rumyantsev, when hundreds of Il-2 aircraft were used en masse to overwhelm the Wehrmacht's ground troops.A theatre offensive can be a war and a dominant feature of a national security policy, or one of several components of war if a country is involved in several theatres such as the United Kingdom in 1941.
