AT Fire at night - no modifier?

[campsawyer]

I was actually thinking more along the lines of armour efficiency not applying at all during night turns. If I am correct in the assumption (and I have made it rather glibly) that no side was markedly superior in night armour fighting than any other, taking armour efficiency away effectively levels the playing field - the only factors in play are the AT fire value and armour value of the units engaged. To me, this seems sensible based on the assumption I've made - if no nation specifcally trained it's crews in night fighting, no-one has the advantage represented by armour efficiency. I'm the first to admit there needs to be some research to back this up, it was just an offshoot of my thoughts on AT combat at night.

My though was for along the line that if an efficient AFV is penalized by the loss of the second shot, shouldn't the non-efficient AFV be somehow penalized too? Otherwise the non-efficient crews have now been elevated to the same level as the efficient crews with just the absence of daylight.
