jul 27, 2038 - a super-strain of malaria suddenly strikes the Horizon Islands

Description:

In 2038, a super-strain of malaria suddenly strikes the Horizon Islands' Tanoa province. The garrison's medical teams quickly offered their support to the local government but to no avail; for unexplained reasons, no known methods of anti-malaria treatments worked to halt its spread.

Simultaneously, the recently-elected pro-CSAT government had begun to grow impatient with the perceived "uselessness" of the NATO presence. CSAT had also offered their assistance to help with the crisis and within days of their arrival, proved to be immensely successful at stopping the disease.

Seeing no reason to keep U.S. forces in the country, the Horizon Islands government mandated the withdrawal of all American personnel. By mid 2038, the last of the Army garrison would be fully withdrawn to make way for Chinese-led CSAT forces.
