Alex and Mueller are OZ pilots who would "execute" allied command bases on earth. When a command base surrenders, the 2 would destroy the entire base with everyone inside. In Mogadishu, the pair assist Zechs in the attack on the base. Although Zechs gets the commander to surrender, the pair don't agree and decide to "decipline" the entire base. As Zechs reasons with one of the attackers, the commander kills the pilot with a well placed rocket. Mueller and Alex blame it on Zechs, Zechs first kills Mueller by splitting him and his Aries mobile suit in half then Alex by ripping him and his OZ Cancer apart.
