Final answer:
Close Air Support (CAS) is a specific form of Counterland military operations focused on providing direct support to ground forces by engaging enemy targets in close proximity to friendly troops. It differs from other types of Counterland operations, such as air interdiction, that target the enemy at a distance and aim to disrupt their potential before engagement with friendly forces.
Step-by-step explanation:
Close Air Support (CAS) is a type of military operation designed to provide direct support to ground forces. It involves attack aircraft engaging enemy targets that are in close proximity to friendly forces. This requires detailed integration of each air mission with the fire and movement of those forces. CAS operations are a component of Counterland operations, which are broader in scope and include all air operations against enemy land force capabilities.
Counterland operations consist of two main elements: CAS and air interdiction. While CAS is focused on direct support to ground troops, air interdiction aims to destroy, neutralize, or delay the enemy's military potential before it can be brought to bear against friendly forces, often at a distance from the battlefield. Therefore, CAS is distinguished from other types of Counterland operations by its immediate proximity to friendly forces and its direct contribution to the ground battle.
