The Cornerian Army is one of the main military forces of Corneria, used to patrol and protect the Lylat System from any and all threats. Squadrons of these soldiers have been dispatched to various areas of the Lylat System to keep the peace. This branch of the military is not to be confused with the Cornerian Defense Force, which deals with threats on Corneria.
In Star Fox 64, the Army is quickly overpowered by the unexpected invasion from the until then unheard of Venomian Army. The Cornerian Army, during that time, had control over Corneria, Sector Y, Katina and Fichina, and they usually managed to endure until Star Fox came to the rescue.
During the time of Star Fox: Assault, the Cornerian Army is able to hold its own fighting rebelling forces, giving Star Fox time to go in after Andrew Oikonny. It is assumed that they, like the Cornerian Defense Force, were severely beaten trying to stop the sudden invasion of the powerful Aparoids. The Cornerian Army base on Katina was among the first victims of the Aparoid invasion.
General Pepper retired and turned his job over to Peppy Hare by the time of Star Fox Command, in which the army must again try to defend Lylat from a quick invasion from a powerful enemy, in this case, the Anglars. Several members of the Cornerian Army are playable in this game, including Bill Grey and Dash Bowman. Krystal also joins the Cornerian Army by this time before defecting to Star Wolf, taking her Cornerian fighter with her and giving it a pink paint job.
