Ally Units or Allied Units, are NPC-units allied with the player that appear in some entries in the Fire Emblem series.
Overview
Ally Units will fight the Enemy Units alongside the Player Units. Ally Units are usually represented by the color yellow or green in the battle UI. Such units act during their dedicated Ally Phase, which occurs after either the Player Phase or Enemy Phase depending on the game. They also may either be named characters or generic units.
In the Tellius Series, the player has a limited amount of control over Ally Units, and can issue them general commands. These commands include 'Target', which allows the player to select a space for the unit(s) to move to, 'Roam', which lets the allied unit(s) move wherever they can, and 'Halt', which prevents them from moving at all.
In Path of Radiance, Tanith is capable of summoning allied units. She can summon up to six ally units (4 Pegasus Knights and 2 Falcon Knights) to help the player during battles.
Ally units, like any non-Player Unit, receive no experience for combat. In Radiant Dawn, however, experience points that Ally Units amass are given to the player as as bonus experience upon the chapter's completion. Additionally, keeping a certain number of Ally Units alive in a chapter often results in rewards that vary by the game.
In the GBA games, Other Units act as Ally units, as they are functionally similar and can fight Enemy Units in support of the player.
