What types of targets is the Avenger designed to engage?

The Avenger is specifically designed to engage and defeat aerial threats, which include both fixed-wing aircraft and helicopters. This capability is crucial for providing an effective air defense system, as these types of targets represent significant threats in many combat scenarios. The Avenger system utilizes Stinger missiles as part of its armament, which are well-suited for targeting aircraft flying at various speeds and altitudes.

Fixed-wing aircraft can include warplanes and transport aircraft, while helicopters represent another category of aerial threats. Engaging both types ensures comprehensive coverage against attacks from above, which is vital for ground forces and critical infrastructure protection.

The other options, while they mention important types of threats, do not align with the primary focus of the Avenger system. For instance, engaging ground vehicles, missiles, artillery, unmanned aerial vehicles, and submarines may involve different systems and technologies that cater to their specific operational engagements. The Avenger's specialization in air defense solidifies its role within the overarching air defense strategy of military operations.
