Night Distribution Percentage

[Dog Soldier]

I would assume that was a night without much moonlight illumination. A full moon would make night navigation very different than your experience.
The game treats all nights the same.

FWIW, I think there should be a little more sophistication for night movement and assault. Moonlight, if known from sources would make a difference. Being in the open desert near Tobruk or on the steppe at Kursk would be different than Normandy. I do not think visibility would be longer from an operational standpoint, just easier on a full moon to navigate behind the lines.
Many times units which had fought were relieved by units in phases during the night. These type of operations appear from what I have read over the years to go smoothly.

Then there should be a case where a firefight leads to a night assault only because daylight ends. These were rare, I suppose and nightfall was usually a time to disengage with the enemy and regroup for the next day. Should there be disruption to pull back on the first night turn?
