How does it not? Consider terrain such as the mountain ranges along the side of California. Or the entirety of Japan. Wheeled and tracked vehicles generally have problems in that terrain. Legged robots don't. Suddenly your troops intended to operate in mountainous terrain have a reliable robot donkey to use as a packmule. Many countries (US, Germany, France, Italy, etc) still use horses and donkeys for transport in bad terrain.
