Japan 45 Campaign

[ComradeP]

I believe the tunnel networks are represented by Trails.

The issue with the increased movement speed isn't necessarily the fact that Japanese units can move additional hexes each turn.  The Soft/Mud condition movement modifiers make it impossible for Speed 4 C quality units to move and assault in any other condition than Normal  The Japanese can at least assault when moving into Clear hexes.

Note: the B quality US units can move and assault as well, but not the C quality units in Japan '46. It makes attacking quite tricky as units have to start adjacent next to Japanese units in order to be able to assault them.
