What does Electronic Warfare (EW) involve?

Electronic Warfare (EW) primarily involves the use of electromagnetic (EM) energy to detect, disrupt, or deceive the enemy's capabilities. This encompasses a range of activities including jamming enemy radar and communications, using countermeasures to protect one's own forces, and employing technologies that disrupt the electronic systems of adversaries. The goal is to gain an advantage in the electromagnetic spectrum, which plays a crucial role in modern combat.

The other options do not capture the specific essence of Electronic Warfare. Psychological tactics on the enemy are part of psychological operations, which focus on influencing attitudes and behaviors rather than utilizing electromagnetic energy. Aerial reconnaissance relates to gathering information about enemy forces and activities, which, while beneficial in a military context, is not inherently tied to electronic warfare methods. Naval warfare strategies involve the planning and execution of naval operations, which again does not directly pertain to the domain of EW focused on EM energy.
