The Knight R1 combines durability and firepower for the Heavy Union, equipped with a 40mm Thumper for robust ground engagements. This unit is easy to field and excels in both offensive operations and defensive postures, showcasing its capacity to maintain frontline integrity via high armor and significant armament.

During the Micro Wars, the Knight R1 became vital to the Heavy Union's control strategy. Created to quickly adapt to evolving combat scenarios, the Knight features the "Thumper"—a compact weapon that delivers powerful, controlled shots. Essential in securing contested areas and establishing bases, these units reinforced the Heavy Union's recovery efforts on Mars. More than just war machines, they symbolize the rebirth of a Martian spirit of resilience, patrolling and protecting settlements across the rugged terrain.
