In Electronic Warfare, which of the following is considered a more aggressive measure?

Electronic Attack is considered a more aggressive measure in Electronic Warfare because it involves the use of electromagnetic energy to disrupt, deny, degrade, or destroy an adversary's capabilities. This can include jamming signals, spoofing systems, or employing destructive capabilities to directly target enemy assets. The primary goal of Electronic Attack is to interfere with the enemy’s electronic systems, making it a proactive action designed to gain an advantage in a conflict.

In contrast, Electronic Support Measures focus on gathering information from the electromagnetic environment rather than actively disrupting it, while Electronic Protection involves safeguarding one's own systems against threats. Signal Intelligence is primarily concerned with the collection and analysis of signals without necessarily taking any disruptive action against them. Therefore, while these other options play crucial roles in Electronic Warfare, they do not possess the same degree of aggressiveness as Electronic Attack.
