Well, we're going to have to work with it I guess. At least we maybe know what MoP was talking about.
Anyways, here's this. I really don't think Myomer is necessary at all.
Design: HLW-12 "Behemoth"
It's time to really put things into gear.
The Behemoth is a massive land vehicle -- comparable to a battleship rather than any existing land vehicle -- that moves itself along the ground using a set of six legs. It has six GA1 cannons on rotating platforms, and GGG-12 nests covering all angles for anti-personnel operations.
It's fairly flat on the surface, in order to save on resource costs. The "bed" is specially armored, in order to avoid a lucky artillery strike from tearing it apart. The "undercarriage" at the front houses the bridge, which is fairly small and is manned by four people -- the captain, helmsman, and two ensigns. It has small glass viewing slits (the bridge relies on visual data relayed via an onboard hardwired comms system [aka cans on a string but slightly more formal] for the most part), and the bridge is fairly armored. Behind that in the undercarriage are the Gavrilium Engines that make this wondrous behemoth possible. Some spartan crew living quarters are arranged (basically just cots with some MREs on a shelf a couple inches away). The top will have lots of sandbags and other fortifications allowing our crew defense.
Minor usage of Gravite amongst the hull allows for a surprisingly relatively light vehicle compared to what you may expect for something of similar size. This plus the Gavrilium Engines gives it a respectable speed (and prevents it from sinking into the ground).
The Behemoth is our first large combat vehicle. A real mobile fortress. It will be best used at the moment as exactly that. Bringing large amounts of troops to the front line, defending them, and serving as a place where we can coordinate our forces from.
