TBD: There was something about fear values above a certain value also increasing the severity of the penalty.
(Possible answer: the manual says that Fear auras increase their check difficulty by 1 for each 5 points of auras strength. But this may be separate from how much morale is reduced?)
TBD: How high is the moral hit
TBD: How do morale hits stack/retrigger?
TBD: Specific recovery rates
(From Loggy's reverse engineering: "The modifier is halved (rounding down) every combat round.")
TBD: How does the squad's collective morale combine for the check?
TBD: For units affected by multiple fear/morale effects, which one is applied each round?
