The Mythical Army, as a special Earth Division Level formation, underwent supplementation and expansion after the Newton Star System conflicts. It now consists of six fully-staffed armored groups, along with a Guard Battalion, a Logistics Camp, an Electronic Technology Camp, an Assault Battalion, a Special Forces Group, and a Reconnaissance Camp, totaling over twelve thousand personnel. During the years Reinhardt served as the Legion Commander, apart from Bonnie's First Group and the rookie-filled Sixth Group, he controlled most of the remaining forces. Particularly, the platoon leaders of these groups' Guard Companies were Reinhardt's die-hard loyalists.
Thus, every soldier in the Guard Companies of the Second and Fourth Group led by Osullivan understood his mission and would execute it without hesitation at the command!
