This stray use of the word "move" appears to be an anomaly in A10.51 v.1. Otherwise the section uses "rout" instead of "move."A routing unit may never move ADJACENT to a Known enemy unit, unless in doing so it is leaving that enemy unit's Location. Otherwise, a routing unit may move toward an enemy unit. Assuming it can abide by the previous requirements, a routing unit must move to the nearest (in MF) building or woods hex (even if overstacked) unless that route is through a Blaze or unbridged Water Obstacle.
