Assault question

[nhill40]

Anyone in the mood to answer a question from a noob?  :)

Mind you, I'm not completely new to operational wargaming, but I am a completely new to the Panzer Campaigns series.  I've been messing around with the free mobile PzC version and I've been able to figure out a lot by reading the manual and just doing a lot of trial & error with the various scenarios.

I doubt this is the only question that will come up for me, but one thing that has surprised me as it relates to assaults is that I can find any evidence/documentation that indicates any benefit from assaulting from multiple directions simultaneously.  I would assume that, all other things being equal, assaulting an enemy held hex from multiple directions would have some kind of advantage over assaulting from just a single hex.

If it is indeed the case that there is no advantage to be gained in assaulting from multiple directions at once, could someone please clue this noob in on why this would be modeled this way in the game?  Intuitively, it seems to me that my life as a defender would be much more difficult if I have to defend in multiple directions simultaneously.
