First Huffman Conflict

In 2070, the USN Army would have a misfiring incident, in which a Cheyenne WAP fired into a crowd within Freedom City, was declared an act of war on the OCU; as an unsolicited use of force. USN Forces denied the use of force as an accident caused by an operation error. The USN, which received the announcement of the start of the war by OCU Forces despite their denial, recognized it in kind by declaring war and mobilizing their forces; Competition over natural resources on Huffman Island was blamed as the real reason behind the war.

Background
Since the time of settlement, both super-conglomerates have been in conflict over two things: the underground resources of Huffman Island and settlement limits between their citizens; about a year after the outbreak of the conflict, the whole island was in a state of immediate tension and paranoia. The USN-side strongly opposed the OCU's settlement on Huffman Island at all and continued to reject the OCU's proposal for talks calling for coexistence. Opinion polls also show that 90% of USN public opinion was willing to use force in the interest of expelling the OCU from the Island altogether.

Ceasefire
As the war winded down The two countries had asked the EC to mediate under a peace and manage Huffman behind the scenes, but the Republic of Zaftra intervened instead and the Huffman Treaty was signed between the two countries in 2071 under the initiative of the PMO.

In 2072, the dispute was formally ended due to the efforts of the PMO mediations in which the USN war situation was regarded as inferior to the OCU. USN agrees with OCU's proposal to establish a formal border near the Mail River. Areas near Freedom City and Peseta were designated as demilitarized zones.

Due to this conflict, the Wanzer's reputation as a general-purpose ground warfare weapon increased even more than it had during the African Conflict 42 years previously, and its introduction (and deployment) progressed rapidly in each country. After the conflict, Huffman Island became active as a cross-border exchange at the private level, and its development as a tourist destination was promoted.

Aftermath
The Huffman Treaty signed between the USN and OCU in 2071 during the first Huffman conflict, Concluded in Moscow. The first international regulation on Huffman Island includes prohibition of the use of all weapons that significantly destroy the environment such as nuclear weapons and chemical weapons on the island, prohibition of inhumane weapons research, division of the island into two territories, and protocols for resource allocation.

In order to protect rare seabirds and abundant resources, Longriver's Island has also been designated as an internationally protected area, managed by PMO, and banned from human habitation or fighting. Although allegedly complied with during the Second Huffman Conflict, a large facility was built on Longriver's Island that served as the development headquarters for Sakata Industries.
