Armor Facing Rule

[Scud]

In a recent scenario discussion, someone mentioned they play with armor facing rules off, to negate the advantage German tanks had against allies. Doesn't turning that option off have just the opposite effect?

I was under the impression that playing with armor facing on, the allied player could negate the frontal axis advantage by getting in close as possible and hitting the German tanks from the rear. With it off, they're murder to destroy from any position.

Am I missing something?

This, from the manual:

The Campaign Series Optional Rule for Armor Facing introduces individual front, side, and rear defense values for each armored unit. These values are based on the standard defense values and hard status, weighted by the actual armor thickness of the vehicles themselves. Hence, they do not represent armor thickness per se, but rather the influence of individual armor thickness in conjunction with the game’s existing values.
