E3N

The Enhanced Tactical Humanoid 3rd Revision (E3N), also known as Ethan, is a character from Call of Duty: Infinite Warfare.

He is voiced by Jeffrey Nordling.

E3N is the robotic companion of Nick Reyes. It is designed to be a "one-of-a-kind" tactical soldier bot, capable of both human emotions and responses. It wasn't initially accepted by most of the Retribution's crew members, especially Staff Sergeant Usef Omar. However, Omar began to like E3N.
