Game play question.

Yes, that's what the manual indicates.

maybe its just my imagination but it seems when firing from a smoke filled hex into another smoke filled hex it decreases  the the firing ability even more.

The Manual says : Smoke – Smoke is an obstacle to LOS if it exists between the firer and its intended target. A unit in a Smoke hex can still fire, or be
fired upon, but only at half Attack Strength. Smoke can be fired only by certain Indirect Fire units, and halves the non-assault attack
into or out of its hex.

So does that mean two hexes with smoke; you're fire is half fire and then halved again firing into the second hex with smoke?

Thanks Ed. 
About my other question. 
Do you think it matters which hex you put your smoke in (as far as, what most protects from op fire). Drop it in the enemy hex or the hex you move into?  I understand from what John said that it seems best in the hex your moving into that way your protected from other adject hexes that might have troops to fire at you. 
But if, there is only one hex containing an enemy unit does putting it in their hex or your hex make a difference?
