According to the Wiki, a vehicle is a mobile machine that transports people or cargo. Typical vehicles include wagons, bicycles, motor vehicles (motorcycles, cars, trucks, buses), railed vehicles (trains, trams), watercraft (ships, boats), aircraft and spacecraft.
I added all of the vehicle types I can think that are reasonably populated and not currently covered. I also added warship & jet fighter for military vehicles.
If there is anything missing from either the regular or military vehicles, please chime in (or edit the request directly [builder+]).

Updated to reflect vehicle hierarchy.
Edit 2:
