 The increase in efficiency depends on mobility used. It costs a 100%
 efficient land unit 6 mobility to raise a sector 1% efficiency.  Less
 efficient land units are charged proportionally higher amounts of
 mobility.  For example, a 50% land unit would be charged 12 mobility
 to raise the efficiency of a sector by 1%.

+6. Supply
 When supply is drawn from a supply unit, that unit pays the mobility
 cost to move the goods to the destination sector.  That cost is the
 same as it would cost the sector to move the goods using the "move"
 command.

 When a land unit is shelled, its mobility goes down in exactly the
 same way that its efficiency goes down (see "info Damage").
