Chopinburg Rainforest

Chopinburg Rainforest is a farmland and forest region located in Central Usea, just west of Axel Bay, Los Canas being located in the center of the territory.

Usean Continental War
On June 1st 1998, Usean Rebel Forces used C-17s to stage a supply line through Chopinburg in the course of the Usean Continental War. In order to lessen resistance in the area, Usean Allied Forces launched an operation to disrupt the rebel resupply line. The Scarface Squadron arrived at Chopinburg in the middle of the rebels' airdrop operation, which was successfully disrupted.

Second Usean Continental War
In the midst of the Second Usean Continental War, ISAF recaptured their main GHQ as well as the city of Los Canas on March 7, 2005. One week later at 3:31 PM, Mobius 1 went on a solo mission in the northern region of Chopinburg to protect two Air Ixiom airliners. These airliners carried engineers responsible for Stonehenge, having been a vital anit-air weapon against ISAF Air Force fighters. They were under attack by Erusian fighters with orders to destroy both airliners, despite having civilian passengers. Air Ixiom Flight 701 was damaged on takeoff and could not climb to safer altitudes, while Air Ixiom Flight 702 maintained flight at higher altitudes. Mobius 1, having to engage fighters at both altitudes, single-handedly shot down all aircraft pursuing the two airliners. With the engineers and their families defecting, ISAF was able to commence Operation Stone Crusher to take out Stonehenge.

Usean Corporate War
During the Usean Corporate War between Neucom and General Resource, Chopinburg was used to conduct joint exercises between UPEO and GRDF, including Nemo participating with Abyssal Dision and Keith Bryan. During the exercises, Neucom dropped chemical containers within the area. With the combined efforts of the UPEO and GRDF, the chemicals, the transport and all escort fighters were destroyed by the UPEO-GRDF force.

Later on UPEO and Neucom joined forces to stop Ouroboros, an organization which was responsible for engineering the war from the shadows to put an end to the corporations. A squadron consisting of Nemo, Erich Jager and Rena Hirose were equipped with Anti-Nanobyte Bomb to destroy a Nano-Byte virus, being developed in Chopinburg. Neucom's nanotechnology research facility in the region had positioned a large quantity of experimental nano-bytes for building/construction purposes. The nano-bytes went out of control and began to spread through the area, breaking down organic substances in order to make materials needed to produce more nano-bytes. The UPEO pilots neutralized the nano-bytes, but Hirose's Su-37 Super Flanker-R had drifted into the range of a Nano-Byte-Ellipsoid and was attacked, driving her to the breaking point in the process. Nemo managed to neutralize the threat at her aircraft and saved her life.
