Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost.
The turning point of the Pacific Campaign of World War II was the naval Battle of Midway, which occurred between June 4 and June 7, 1942.

Air, naval, amphibious, ground, and logistical forces were all necessary, as were land bases for both staging forces and as forward areas.
