In Fenrir, God Eaters are divided in units. In the Far East Branch, Units are named with ordinal numbers. There are three notable Units;the 1st Unit (Retaliation Team), the 2nd Unit (Defense Team), and the 3rd Unit (whose original purpose is to defend Aegis Island, but most likely became a Research/Reserve Unit). There was also a 7th Unit mentioned but its members remain unknown as the unit itself only had a single mention during the course of the game (although it is heavily implied that the 7th Unit is actually just a cover for Lindow Amamiya when he goes to secret missions). Note: These ranks are those that appear after completion of the Burst story arc of God Eater Burst.
