2536


 * Covenant forces begin to swarm into the Inner Colonies. For several years the war falls into a pattern: the UNSC wins isolated battles, typically during ground operations, but at a horrible cost. In space, the humans are losing at a precipitous rate, and one by one, the Inner Colonies fall.
 * Hayabusa Powered Assault Armor is developed by Facility RKD and accepted by the UNSC Ordnance Committee late in this year.
 * October-November: SPARTAN-III Alpha Company graduates and is deployed into combat.
 * An insurrection on Mamore, the Battle of New Constantinople and several conflicts in the Bonanza asteroid belt and the Far-gone colony platforms are fought either late in this year or 2537. SPARTAN-III Alpha Company distinguishes themselves in these engagements.
