yes.  it doesn't have a unittype or move_rate, something very vague to 
give idea of the distance from the city to surroundings.

igter_move is self-explaining init?  move_cost across any land is 
MOVE_COST_ROAD.

all this is to say that there are more types of BMC than 
enum unit_move_type

well divide total_moves_expended by the move_rate and you get your limit.

not sure.  ask.
