Very interesting design. But I somehow question the idea that the fuel tank is to be located on the front. After all this is where a military vehicle gets shot at most often.
I see you added lots of armour on the back so it can run away with the best chances of survival... but scouts need to be able to do attack runs on unprotected targets and then this could be dangerous...
this is awesome, though i'm unsure about that fuel tank... seems a little small compared to the vehicle (unless of course it is just "the tip of the iceberg"), and is in a rather vulneralble position IMHO.
anyways, that might just be me. the amount of detail on that thing is impressive.
