All races includeing expansions will have access to the core set of vehicles. This is for basic playability. Each race (including the two core races) will have expansion units that will replace one of the core units for that race. The expansion unit will always be a bit better to encourage purchases to improve armies. I look at it like the core units are really old technology and expansion units are new technology.

Off the top of my head - please add, also note we can use different names!

Ships (major)
Battleship
Cruiser
heavy freighter
medium freighter

Ships (minor)
fighters
drop ships (cargo haulers)

Vehicles
Heavy Tank
Medium Tank
Troop Hauler

Troops
Grunts
leaders

Structures
Wall
Gate
generator of some kind
pill box
tower (for wall)
generic building (for possible other uses like armory, barracks etc etc)

thoughts?
