What potential effect does effective Electronic Warfare have on enemy capabilities?

Effective Electronic Warfare (EW) focuses on disrupting or degrading an adversary's communication, navigation, and surveillance capabilities. The correct choice emphasizes the protective measures that EW can provide to friendly forces. By jamming or interfering with enemy communications, friendly capabilities can operate more securely, reducing the risk of being compromised by electronic threats. This protective aspect enhances the ability of friendly forces to maintain situational awareness and execute operations without interference from enemy electronic capabilities.

In contrast, the other options do not accurately reflect the primary impact of effective Electronic Warfare. While it does not increase an enemy's communication efficiency or reduce their need for encryption, it is more about suppressing their capabilities and maintaining an advantage. The goal is to compromise enemy operational strategies rather than support them, which further highlights why the correct choice accurately represents the intended effects of effective Electronic Warfare.
