Which of the following best describes an example of Electronic Warfare capabilities with foreign weapons systems?

The option highlighting radar jamming, electronic countermeasures, and cyber capabilities is the best descriptor of Electronic Warfare (EW) capabilities related to foreign weapons systems. Electronic Warfare encompasses the use of the electromagnetic spectrum to disrupt, deceive, or deny enemy operations while protecting friendly forces and capabilities.

Radar jamming involves sending signals that interfere with radar systems, thus protecting forces from detection and targeting. Electronic countermeasures refer to a range of techniques used to confuse or deceive enemy sensors and communications. Cyber capabilities involve the use of digital networks and information systems to gain an advantage over adversaries, whether by attacking their systems or gaining intelligence. Together, these elements represent the core activities and objectives within the realm of Electronic Warfare, which aims to control the electromagnetic spectrum to ensure operational effectiveness.

In contrast, the other options describe capabilities that do not directly pertain to Electronic Warfare. Night vision and thermal imaging fall under advanced surveillance and targeting technologies, missile guidance systems focus on precision targeting rather than electronic interference, and ballistic protection and armor enhancements relate more to physical defense than to manipulating electronic systems.
