Example: In a tactical map looking (in part) like this (assuming
combat units are present throughout):
A unit at 4-2, on the north/east bank of the river, can march in seven directions: all but southwest. To march southwest it must first move to the south/west bank of the river (or to the ford; ford squares are on both banks). If it moves south or west, then it must remain on the same bank of the river it is currently on (north bank if it moves west; east bank if it moves south). Its entry square will be adjusted if necessary. If the unit moves northwest, north, northeast, east, or southeast, its movement is unconstrained by the river.
A unit at 3-5, on the south/west bank of the river, can march in
directions: west, southwest, and south. If it marches in the other
directions, it must first cross the river. If it moves south or
must remain on the same bank of the river (west bank if it moves
south bank if it moves west) and its entry coordinate will be
If it moves southwest, its movement is unconstrained by the river.
A unit moving strategically also cannot depart from a marsh square when enemy combat units (non-HQ units) are present, unless it is located near the appropriate edge/corner of the tactical map. A unit moving north must be within 3 squares of the north edge of the map; that is, in row 3 or further north. A unit moving east must be column 11 or further east, a unit moving south must be in row 11 or further south, and a unit moving west must be in column 3 or further west. A union moving diagonally must be within 3 squares of the corner of the tac map in the direction it is moving. A unit moving northeast must be in row 3 or further north and must also be in column 11 or further east, and similarly for the other three diagonal movement directions.
