Which of the following systems is targeted during SEAD missions?

In Suppression of Enemy Air Defenses (SEAD) missions, the focus is primarily on targeting Command and Control (C2) systems. These systems are critical for an adversary's ability to coordinate and manage their air defense infrastructures, such as surface-to-air missile systems and anti-aircraft artillery. By disrupting or destroying C2 capabilities, friendly forces can gain air superiority and make it more difficult for the enemy to respond effectively to air operations.

C2 systems serve as the brain of the air defense network, enabling situational awareness and the ability to make real-time decisions. When these systems are targeted successfully, it diminishes the enemy's reaction capability and allows for safer and more effective operations for friendly aircraft.

Other options involve elements that could be targeted in broader combat operations, but they do not specifically represent the focus of SEAD missions. Ground troops may be affected indirectly, and while airborne radar arrays and communication satellites are significant, they are not the primary objective of SEAD, which aims to degrade the enemy's air defense network specifically through the disruption of C2 systems.
