The ground war on Lucerne Planet was fiercely raging, with the Leray Federation, backed by strong logistical support, using the Miloke Binary Stars as a forward base. A total deployment of fifty-one fully mechanized infantry divisions and thirty-six armored divisions amassed a force of over 1.8 million troops. They occupied most of the Western Hemisphere and the Elephant Mountain line in the Eastern Hemisphere of Lucerne. Four army groups totaling one million troops launched attacks on Amayo Mountain, East Valley City, Razi Defense Line's Luofeng Mountain Pass, and Rotersk City.
