The Freedom and Liberation Party was established on Mamore to achieve total independence from the UEG. A paramilitary wing of the FLP fought a bloody conflict against UEG presence in the colony. In 2511 the FLP detonated a nuclear device in the Haven Arcology, killing two million people and injuring a further eight million. Per Operation: TREBUCHET the UNSC increased its garrison to aid in counter-terrorism operations. The UNSC failed to achieve a lasting success, and in 2537 the SPARTAN-III Alpha Company was deployed to assist in operations. As late as 2552 the UNSC was relying on Spartans such as SPARTAN-B312 to assist in operations.
