Defense of Concord
From Halopedia, the Halo wiki
The defense of Concord was an engagement of the Human-Covenant War in 2551 between the United Nations Space Command and the Covenant on the human colony planet of Concord. During the battle, several test models of the MJOLNIR Powered Assault Armor [GEN2] were utilized, albeit without their full combat suites. Notably, the VENATOR-class Mjolnir—manufactured by Concord's Lethbridge Industrial—gained prominence during the defense of Concord due to the armor's effectiveness in hand-to-hand and single-enemy combat.
The engagement likely resulted in a victory for the UNSC, as Concord survived the Covenant War and remained inhabited shortly after the war.
