(10) The official explanation for the Zaku II's cables is that they transmit hydraulic power to actuators in the mobile suit's joints. This always struck me as absurd, for why would the Zaku need to transmit hydraulic power from its belly to its backback, or from its muzzle to the back of its head? Likewise, early mobile suits like the Zaku II and the Gundam are usually said to use traditional chemical rocket engines, but this seems to defeat the purpose of having a thermonuclear reactor in the first place.
