The operational organisation of the UNSC was, in 2525, structured in a way that best allowed it to fight widespread, low-intensity insurgency, and so emphasised aggression, small unit tactics, flexibility, amphibious capability and rapid response. This was quickly proven to be inadequate in combating the Covenant, a far numerically and qualitatively superior foe. A drastic restructuring took place between 2530 and 2535, spearheaded by those officers with most operational experience of the Covenant's tactics, such as Admiral Cole, and intended to reshape the UNSC Navy into a force that could most effectively meet the Covenant in battle.
