For the heavy stuff they definitely had direction, there should be bonuses to defense from all angles but at a reduced level for those not facing the enemy, the rear being the most vulnerable.
A counter down would be cool, the longer a defense was unsupplied the worse it got, the Maginot line did have a lot of food rations, but it was considered a level 10 fort, so for simplification purposes, it will loose it's bonus over time.
I am also in heavy favor of a fort having to have a special kind of Garrison. At least for the higher level forts. Not every GI JOE can properly man a fortified 105mm Howitzer.
Come to think of it, it doesn't make sense to give a standard defense bonus to any units normal stats for higher level forts. Any troop or panzer would benefit from nice sets of trenches or dugouts. However, not from a fortress. There should be a break off point where it goes from being nicely prepared defenses to an all out fortress. Extra troops help, but you are not going to have a division sitting inside a fortress helping that much.
