What is the name of Chrom's personal army in Fire Emblem Awakening?

Chrom's personal army in Fire Emblem Awakening is called the Shepherds.

The Shepherds serve the Halidom of Ylisse, a nation devoted to the Divine Dragon Naga. Although Chrom is the prince of Ylisse, the group functions as a mobile military force rather than a conventional royal army. Its members defend villages, fight Plegian forces and confront the undead Risen threatening the continent.

Robin joins the Shepherds after Chrom and Lissa find the amnesiac tactician in a field. Other important members include Frederick, Sully, Stahl, Vaike, Sumia and Maribelle, with additional allies joining as the story progresses. The group also becomes central to Chrom's later campaigns against Plegia, Valm and the Fell Dragon Grima.

The name is easy to confuse with other Fire Emblem factions. The Greil Mercenaries belong to the Tellius games, while the Blue Lions are one of the three student houses in Fire Emblem: Three Houses. The Four Hounds are antagonists in Fire Emblem Engage, not Chrom's soldiers.
