A chain of mountains where the rebel plane "Tetsuyuki" crash-landed. This level features many huge seafaring vessels marooned in places they could not realistically travel to, such as a large regular army submarine of unknown origin stranded in the middle of a dried and (relatively) shallow riverbed, and appears to be an oil tanker trapped in a lagoon beneath a waterfall where the Tetsuyuki was located.
This stage is presumably located in Southeast Asia, due to its jungle environment and a large Siamese/Cambodian idol encountered at the beginning of the level. This is further evidenced in Metal Slug Defense. When selecting the Southeast Asia level, the backdrop shows the Villeneuve Mt. System.
