Air interdiction

Air interdiction (AI), also known as deep air support (DAS), is the use of aircraft to attack tactical ground targets that are not in close proximity to friendly ground forces. It differs from close air support because it does not directly support ground operations and is not closely coordinated with ground units. Unlike strategic bombing, air interdiction is not meant as an independent air campaign, as its ultimate purpose is to aid ground operations rather than to defeat the enemy by air power alone.
