Defensive missiles are critical components of modern military strategy, offering countries protection against potential threats from adversaries. These missiles are designed to intercept and destroy incoming threats such as enemy missiles, aircraft, and drones, before they can cause damage to a country's infrastructure or population. There are several synonyms that can be used to describe defensive missiles including anti-ballistic missiles, surface-to-air missiles, and air defense missiles. These synonyms all refer to specific types of missiles that can be launched from the ground or air to defend against incoming threats. Whether used to protect a military base or a major metropolitan area, defensive missiles play a critical role in bolstering a country's national security.
