I'm playing this scenario for the first time, and am confused on what to do when contact occurs. For example, I'm playing the Americans, and I move to a spot where neither stack of Germans can see me (> 2 hexes away at night), and place a "moved" marker on my stack. What happens if a German stack, using the random patrol movement method defined in the scenario moves within 2 hexes of me? Do they have to continue moving or do they stop...? or move to melee or cover?
