The host explained at the right moment: "The War Spider Guards had suction pads on their feet, which allowed them to easily adhere to the surface of buildings.
"In the process of moving, at least three legs use the suction pad function, almost never falling off, thereby achieving the effect of walking walls and roofs.
"The mechanical dog only has four legs, even with suction pads installed, it can only activate two suction pads when moving, leading to naturally less stability.
"Everyone knows that cities are full of buildings and the environment is very complex, so War Spider Guards are more suitable for urban warfare.
"In comparison, although the mechanical dog runs faster, it doesn't have much advantage in the city.
"Another option is drones, but drones also have limitations.
"In severe weather conditions like a storm, the stability of small drones isn't good, and accidents are very likely.
