A new skill learnt, should PzC go the same way?

I remember a game Operation Crusader
http://www.mobygames.com/game/operation-crusader

Aside from the different types of attack available, the New Zealand Division had a speciality of being more able to attack at night because they had trained for it.
Not sure if that was true IRL but it made the game interesting.
Can anyone remember this? Not sure it brings much to the discussion except that selected units even in WWII were good at it (or turning it on its head, the least worst?) *assuming they did train for night attacks in reality...*
