House Rule: I reduced the American marines INF to 9-5/5-5 for this scenario.

Played solo in less than 90 minutes.

I set up the two Japanese entrenchments far north with a small screening forces (2 units and 3 leaders) in front on them. The idea is very simple; to delay the American advance 1 or 2 turns.

The Americans make contact with the screening force on turn 6 and assault them the next turn. It takes two turns to eliminate them and there are only 8 turns to take control of the two entrenchments. The Americans take control of the first entrenchment on turn 13 but the flamethrower unit is disrupted and lose a turn recovering. The other entrenchment still has 3 steps of defenders when the engineer joined in the assault. The Japanese lose 1 more steps but both reduced units passed their morale check. The Americans need a "4" or better on the last assault but roll a "1".

Japanese victory.

I gave this scenario a "3". Not many decision points but they are critical as the Americans are fighting the clock as much as the Japanese.
