The AT-ST can't attack players that are adjacent to it. This lead me to two questions:
1. Does the adjacent player block line of sight to a character behind the player? Since the AT-ST can't see the player to shoot him, I ruled that the player can't block line of sight.
2. What if the AT-ST wants to move into that player's space? Does the AT-ST push the player out of the space, or does the player prevent the AT-ST from moving into that space?
Haha, I really wanted there to be a rule that the AT-ST could just step on the player...but I just decided not to move him into the space.
