Flank Morale Modifier

[BigDuke66]

From the reality perspective it seems rather realistic that a unit that is "anchored" on both sides to be more steadfast.

From the gaming perspective one shouldn't forget that even a failed assault will lead to the defender being at least disrupted and that leads to the moral being one level lower again so the next turn that unit is more vulnerable.
I don't mind the flank moral bonus because there are many modifiers that can lower the moral but few that can raise it, right ow I can only remember flank moral and having a leader in the same hex giving a raise of moral, all other things lower it.
