The Big Picture documentary The Steel Ring explores the steps the Army took to help alert us to threats in the era of atomic weapons. Since such an attack can come at any time with very little warning, the Army made it a mission to get as much advance warning as possible to protect the American homeland. This includes building a series of defense lines comprised of radar and guns to surround our cities and country and provide a line of defense against incoming deadly missiles.
