With three Battalions of Heavy Mecha at their backs, the Klem began to charge for the center. In their minds, since breaking free of the confinement didn't distract these hateful metallic monsters, and their attacks didn't draw more defenses to any particular spot, that meant that the leader was clearly the one in the center. Once Fifth Battalion was reassigned to Max's position, it cemented this notion in the minds of the Klem.
If they could overrun the position in the center, the Klem were certain that the Mecha organization would crumble and they would be left leaderless and weak. In the past, they had fought enemies that had turned even more vicious when the leader was killed, but going by the way these Mecha were organized by size, the Klem had decided that they were a Caste-based enemy, so their leader should be very important to them.
