1. Does this mean that you add SF markers in addition to or instead of firing?We played our first game (actually 2 games) last night and used this optional rule. Our interpretation of 94.0 is that it is an augmentation of both designated fire and Op Fire (but not Final Op Fire). At the time the actual fire takes place the firer is marked with both a Used and Sustained Fire counter (which I wouldn't bother with in the future; the SF counter seems sufficient to identify that the firer is also used). The target hex and one eligible adjacent hex is also marked with an SF counter) and for the remainder of that turn that unit's Final Op Fire can only occur in the designated hexes.
2. May SF markers be placed regardless of the type of fire (normal, op, final op)?I don't believe it would be placed for Final Op Fire and in most cases wouldn't really be beneficial. After all, there is no limit to the number of times a unit can Final Op Fire. The only case I can think of where it might be useful is if the firer had paid 1CP to Final Op Fire at a range of 2 instead of at an adjacent unit.
3. What happens when firing at a hex that has one unit with a concealment marker and one without?I would apply the one die-roll rule and simply apply different modifiers to each result. After all, even with one die roll the target units might have different Casualty numbers and would have to be evaluated separately. Similar situations would occur if firing at a hex with infantry units or guns that are both in and out of a foxhole, a hex that contains both a mounted and unmounted infantry unit, firing with an intrinsic SATW at a hex with both an infantry unit and a gun/WT, or at a hex with both an infantry unit and a vehicle with a rear vulnerability.
