There were many types of mobile armors. The Jungle Ranger, as the smallest mobile armor, had two operations. One was a portable operation. Almost everyone who used the Jungle Ranger will use the numerical control operation, which basically won't consume any of the operator's power.
The Jungle Ranger had another operation, which was a pure manpower operation that was rarely used even by the drive furnace. Many people liked to call the initial development of these types of mobile armor, a force armor. The Jungle Ranger was like an ancient knight's armor equipped with various weapons, it could even be said to surpass huge mobile armors.
Its arms wrapped around the operator's arms, its legs wrapped around the operator's legs, and its body also wrapped around the operator's body. It was not like other mobile armors that required a cockpit.
