Concept design for a futuristic tank. I gave it hydraulic suspension and a vertically-launched missile system as its main weapon in order to keep its height as low as possible - 1.8 metres with the suspension fully lowered and the turret not deployed. This makes it harder to hit and transportable by shipping container. The gun turret can be raised up to fire from behind cover. It's powered by two large hydrogen fuel cells (mounted over the front tracks) driving twenty hub-mounted electric motors in the wheels. The large blue cannisters in the rear are hydrogen fuel tanks. The two crew don't have any windows but see vio VR headsets and backup flat-panel displays. All the driving and weapons controls are fully duplicated between the two crew stations in order to allow the most efficient division of tasks between the crew in a given tactical situation.
The missile system is in a self-contained module, containing 4x6 "Wolverine" surface-to-surface missiles, 4x5 "Storm" surface-to-air missiles, or any combination thereof. Missiles can be reloaded either individually, in 4- or 5-unit pods, or en masse with replacement of the entire module.
The weapons module itself can be replaced entirely with a railgun turret modue, a mortar, a passenger compartment carrying six troops, a command unit, or an ambulance unit.
