Rainforest Wars

The Rain Forest Wars were a series of bloody conflicts between United Nations, Koslovic and Frieden forces in 2162.

Background
In 2162, following the Jovian Moons Campaign, armed conflict ripped through South America as Koslovic, Frieden and UN forces clashed over ideological differences, sparking additional conflicts off-planet, such as the Argyre Planitia Campaign. This war brought a great deal of suffering to the people of Earth, and caused an enormous famine.
