What does Electronic Attack (EA) primarily involve?

Electronic Attack (EA) primarily involves the use of electromagnetic (EM) energy and directed energy weapons to disrupt, degrade, or destroy enemy capabilities. This can include a variety of tactics such as jamming enemy radar, disrupting communications, or blinding enemy sensors using high-powered microwaves. EA focuses on manipulating the electromagnetic spectrum to achieve strategic advantages over adversaries by targeting their electronic systems.

In contrast, other options describe different aspects of military operations. Attacking enemy personnel and facilities with physical weapons relates to conventional physical attacks, while managing the electromagnetic spectrum for friendly operations pertains to electronic warfare strategies focused more on defense and coordination rather than direct offensive actions. Defensively protecting friendly forces from enemy attacks suggests a defensive posture, which does not align with the offensive nature of Electronic Attack. Thus, the focus of EA on utilizing EM energy as an offensive weapon makes the second option the correct answer.
