We had an opportunity to play a scenario from WO18, Deluxe scenario Dew of Death which pitted Japanese against Chinese, a run through situation spiced up with poison gas. Chinese 1st class troops have certain disadvantages even without the harassing poison gas.
Terrain has very limited cover since all forests are brush. Buildings are clustered such a way that they can be subject to the poison FFE rather easily. Because of the 1MC FFE, defense needs to be spread out. Chinese have broken morale of 6, so any hope to have them recovered once they lose it is very unlikely.
Japanese do not have much time, and they have to exit a lot of troops, so if Chinese can make Japanese to pay for every step, however lightly, they will not make it. Hence, I planned to take advantage of every single 1.5FP shot I could muster if I would benefit from FFMO.
