Another One

[Nitram Draw]

Well, this is a fresh Moral A, Fatigue 15 unit. A similar one finished its bridge on south after 1 turn. The elevation is different, I've just noticed: 160m on one side and 180m on another. May be this is the case?

What is "modifier for a COY vs a BTLN strength unit" unfortunately I do not understand yet.

Morale gives an increased chance (A morale is 20% better I believe) of completing the bridge.
If the under is less than 100 men you have a percentage reduction, 90 men = .9 X standard chance, of completing the bridge.
If the engineer unit is company size, either broken down or is just a single company then it has 1/3 the normal chance of completing the bridge.
So an A morale company of 90 men would have the standard chance of building the bridge on a given turn multiplied by .356.
An A morale battalion of over 100 men would have the chance multiplied by 1.2.
An A battalion with 80 men would have the chance multiplied by .96.
