Developed in Portugal, this particular mech was good for two roles: clearing large trees to make way for heavy artillery to move forward in the South American jungles, and guerrilla attacks on enemy convoys. They were influential in preventing crucial weapons caches from being reached.

An old legend in the enemy camps says that the O-7s were possessed by the ghosts of dead warriors from long ago.
The O-7 was very good for hiding in different areas and blasting hostile vehicles, while stomping on enemy soldiers. However, the model O-7 ended up being retired after the end of the series of jungle conflicts.
This particular O-7 was generously donated by the Portuguese Foundation of Historical Preservation. It was used in the Venezuelan Battle of 2055, suffering heavy battle damage. Today, it has been restored and is on display at their museum in Lisbon.
