Unit Movement

All units move vertically and horizontally but not diagonally on the map.

Unit "Speed"

Every unit has a budget of speed (movement) point which it can use during one turn. Each move from one square to the next "costs" the unit a number of these points until the budget is depleted (although of course units are not required to move the full distance). The cost for moving from one square to the next is determined by the terrain of the square, by roads or railroads that might be available, by changes in elevation and by some other square properties (such as bridges). 

Example: Unit A has a budget of 6 for movement in one turn. If the cost for moving on grassland terrain is 2 then the unit could advance three squares before it is out of moves (see example on the right).

Locked Terrain

Not all units can travel on all terrain types. Each scenario has its own unit types defined and this definition includes the terrain types that can be used by the unit. A ship would of course only be able to access water squares. A tracked vehicle is land-bound but might have some additional capabilities (such as moving in shallow water). Look in the scenario descriptions to find out what units are available for a game and what terrain they are able to access.
