E3N "Ethan"

Petty Officer First Class Enhanced Tactical Humanoid 3rd Revision (E3N) (A.K.A. Ethan) is the tritagonist in Call of Duty: Infinite Warfare.
E3N is designed to be a "one-of-a-kind" tactical soldier bot capable of human responses and emotions, making him significantly more advanced than standard C6 robots, which are little more than mindless drones. Initially, he is not accepted by some of the crew members, especially Omar, though even Omar grows to appreciate him over time.
==Biography==
===Geneva Attack===
Before the attack, Ethan was mentioned by an unnamed Petty Officer, that "it" was already on the roof and ready to fly to the ceremony. At the Raven, Raines mentioned that Ethan was supposed to be introduced at the Fleet Week Ceremony. Ethan was the first to notice that the AATIS guns appeared to be tracking their fleet.
Surviving the barrage, Ethan, Raines, Reyes, and Salter retook the tower and stopped the AATIS guns from self-destructing. Ethan boarded Reyes' Jackal as co-pilot and launched to destroy the rest of the remaining SDF Fleet that invaded earth. Unfortunately, despite successfully destroying the remaining SDF Warships, the remainder of the UNSA Fleet was ambushed by the SDF supercarrier Olympus Mons, resulting in only two ships surviving, the Retribution and Tigris.
===Operation Port Armor===
After being ambushed by the Olympus, Ethan, Salter and Reyes landed on the Retribution. Raines tasked them and the Marines to take back the Lunar Gateway Port on Luna before SetDef could destroy it. Ethan also meets Staff Sergeant Omar for the first time, who doesn't take kindly to him and unsuccessfully argues that Ethan should not be brought along for the mission. Ethan helped the Coast Guard and the Marines take back the facility and save civilians in the process before boarding a Jackal with Reyes and destroying the attacking SetDef ships.
===Operation Burn Water===
Omar's opinion of Ethan shifted and the former requested he be included on their upcoming mission to Titan to take out SDF's Primary Fueling Tower there. Once they landed on the surface, they sneaked through the SetDef's perimeter undetected and identified a good LZ. Raven dropships arrived and supplied their ground force with two SATO APCs, and a C12.
Utilizing the C12, the team was able to make good progress until the C12 and their APCs were disabled by an enemy Mega. Reyes managed to destroy the Mega and Ethan rebooted their C12. Shortly afterward, the Olympus Mons jumped to their location and inflicted heavy casualties on the ground force, including their C12.
The Retribution arrives and is able to launch several Jackals and engage the Olympus Mons to give the ground force a chance to continue. They managed to fend off enemy Skelters and an A-Jak which had entered the fight. Ethan and Reyes then stormed a nearby facility, eliminating the personnel within and using the controls to overload a nearby fueling tower. Returning to their Jackal, they are able to destroy the fueling tower and the rest of the refueling station via a chain reaction. The Retribution then returned, and attempted to exfil all friendly forces. Unfortunately, the Retribution had not completely evaded the Olympus Mons and was taken by surprise. Ethan and Reyes' Jackal was shot down during the engagement forcing Reyes to order the Retribution to make an emergency jump to safety, leaving himself and Ethan behind. Reyes' suit had been punctured during the fight and rapidly depleted its oxygen supply causing Reyes to black out. Fortunately, Reyes and Ethan were rescued by the UNSA Tigris which was able to locate them. Captain Ferran of the Tigris wryly remarked that when they found the two, they'd had to pry Ethan's arms from around Reyes as Ethan's arms had frozen in place, protecting his captain.
===Assault on SetDef's Orbital Shipyard and Sacrificial Death===
Just seconds after Raines was killed by Kotch, Ethan appeared before Reyes in a Jackal, requesting he get on board. Under Reyes' command, Jackals launched an assault onto the Olympus Mons, intending to seize the enemy vessel and kill Kotch. The team fought their way through the ship, eventually reaching a sealed door that led to the bridge. Ethan suggested that Reyes use a hacking module to hack one of the C6's and wipe out the resistance in the room and the plan succeeds leaving Kotch, the only survivor, severely wounded. Ethan reprogrammed all the remaining C6's and C12's on the whole vessel, placing them under his direct command, instructing them to salute Reyes as he walked onto the bridge. Reyes then finished Kotch off leaving the supercarrier under their control. Reyes then instructed the crew to plot a course to Mars.
Once the Olympus Mons arrived, Ethan activated the ship's F-Spar cannon and gave Reyes control of it. Although they were able to destroy many SDF ships, a hostile boarding party damaged a section of the ship, disabling the cannon before they were driven off by UNSA troops and Ethan's bots. Ethan began flying the carrier towards the orbital Shipyard with the intent to destroy it via ramming, and the Retribution jumped in to provide cover fire. Both the Retribution and the Olympus Mons were badly damaged, and ended up colliding with each other despite Ethan's attempts to maneuver out of the way. Before the ship crashed onto Mars, Ethan took as many C6s and C12s out of the ship as possible via dropships. Reyes planned to have Ethan use the bots for a diversionary attack and then use the still-functioning cannons on the Olympus Mons' wreckage to give the rest of their force cover as they boarded a space elevator to the SDF shipyard in orbit.
Once aboard the shipyard, they planned to take control of an enemy destroyer. Unfortunately, the destroyer's weapons were locked and would not function until authorization was given. Reyes and Ethan planned to take the command center and transmit the authorization while Salter, with the rest of their remaining crew, boarded the destroyer and used its weapons to cause as much damage as possible. Taking the command center, they were able to grant weapons authorization but found that the mooring clamps had been locked in place. To unlock the clamps, Ethan planned to enter the nearby power core and disable it, however, he needed Reyes' to remote hack his body as the electromagnetic radiation from the core might disable his motive systems. Once there, Ethan sets the core to overload but states that it would need a charge to set it off. Ethan reminded the captain that his self-destruct sequence would be enough to destroy the locks and free the SDF Destroyer. Reyes sadly sacrificed his "brother", allowing the SetDef ship to break its mooring and attack the shipyard. Ethan's actions allowed Salter's crew to destroy the shipyard, crippling the SetDef fleet and forcing them to end the war.
His name was not on the memorial wall listing fallen UNSA soldiers despite his extraordinary contributions, as his existence was kept secret from the public.

===Trivia===
*Ethan appears as a Supply Drop unlockable full Synaptic rig, donning a greenish color scheme.
*According to Taylor Kurosaki, one mission that was cut from the final game would involve Ethan and Reyes having to survive by jumping between giant hunks of space debris, involving firefights from multiple orientations. While this mission was ultimately cut, it does nonetheless appear briefly in the game's reveal trailer between 2:31-2:36.https://twitter.com/taylorkurosaki/status/1186341177806581762
*Ethan's head can be found floating in space during the credits.https://www.youtube.com/watch?v=PhETObg80oY
