E3N "Ethan"

The Enhanced Tactical Humanoid 3rd Revision (ETH.3n), also known as Ethan, is a character and American robot in Call of Duty: Infinite Warfare. He fights alongside Nick Reyes.

ETH.3n is designed to be a "one-of-a-kind" tactical soldier bot, capable of human responses and emotions. Initially he is not accepted by some of the crew members, especially Omar.
