Which division of Electronic Warfare (EW) focuses on protecting friendly forces from enemy electronic attack efforts?

The correct answer is that Electronic Protection (EP) is the division of Electronic Warfare that concentrates on safeguarding friendly forces against enemy electronic attacks. This aspect of EW is essential because it involves measures and techniques designed to ensure that communication and data integrity are maintained in the face of hostile interference, jamming, or other electronic threats.

Electronic Protection encompasses various methods to enhance the resilience of friendly systems against such electronic threats. This can include encryption, frequency hopping, and other countermeasures that either make it difficult for the enemy to disrupt communications or allow friendly forces to operate effectively despite an attempt to impair their capabilities.

The other divisions mentioned, while integral to the broader scope of Electronic Warfare, serve different roles: Electronic Warfare Support focuses on gathering intelligence regarding enemy electromagnetic activity, Electronic Attack is aimed at disrupting or destroying enemy capabilities through electronic means, and Signals Intelligence involves the collection and analysis of enemy signals, but does not specifically address the protection of friendly forces from electronic attacks.
