Following the Invasion, Johnny Rico was demoted to colonel and transferred to a Martian satellite. His primary responsibility on the satellite was to train a new group of soldiers, although they struggled to perform due to their apathetic attitudes resulting from their Martian background. The entire planet of Mars was not supportive of the war and suggested withdrawing from it due to their lack of involvement. Their lack of preparation led to their vulnerability in the face of the bug attack. In the meantime, Sky Marshall Amy Snapp had her own hidden agenda for gaining power.
