Ethan Ryer

Captain Ryer is a Federation officer in charge of the troops in Eastern Asia, where the Kojima Battalion is located. He makes his appearance later in the series once he suspects that Shiro has betrayed the Federation and distrusts him for the rest of the series. He even goes as far as to have Karen and Sanders spy on him, and sends out a sniper to kill Shiro when he deserts the Federation forces. He attempts to destroy the Zeon's base through the detonation of the nuclear engines of his own force's mobile suits. He also orders the destruction of the Kerguren, occupied by many wounded Zeon soldiers as its taking off.
