Ian Dietrich

Ian Dietrich (イアン・ディートリッヒ) is a member of the Garrison in Trost District.

Story
Ian first appears after Trost District is breached by the Colossal Titan. He orders Mikasa to support the rear guard before she protests that she will only slow them down. Ian retorts that he didn't ask for her opinion and says she should just obey. He later compliments Mikasa for killing a Titan that was attacking a group of evacuating civilians.

When a plan is formed for Eren to use his Titan powers to seal the breach with a boulder, Ian is placed in charge of the elite squad assigned to protect Eren on his mission.

When Eren loses control of his Titan form,Rico advises Ian to abort the mission and retreat. However, Ian orders his soldiers to continue to defend Eren down to the last man, as Eren is their only hope against the Titans.

Eren regains his senses due to Armin's intervention, and Ian orders his soldiers to protect him until he reaches the breach even at the cost of their own lives. Ian uses himself as bait to lure Titans away from Eren, sacrificing his life in order to ensure the success of the mission. He died after pulling a squad member out of a Titan's mouth, in a manner similar to how Eren saved Armin, but was eaten and killed when it pushed him into his mouth in such a way that his head was bitten off by it.

Abilities
He is a highly capable soldier, and his leadership was trusted enough to earn him command of the Trost mission.
