Wait until you try to figure out RFP for Guns/MA fire. It gets a little funky in the feel of it as once a hit has been achieved you would think the RFP is based only upon the FP used to conduct the attack; however you must go back and remember how many hindrances affected (or could have affected) the TH shot to determine the actual RFP placed. It really gets a little weird when you shoot at a target in a stone building hex bordered by a wall. Even though the wall did not effect the shot, to determine the RFP placed in the building, you would have to reduce it two standard columns because the wall could have affected the shot. Another one that feels funky is RFP already placed in say a building hex that you are bypassing. Intuition would tell you that since the moving unit is in the open (most likely) FFMO would apply to the RFP shot. However, as Robin pointed out RFP has no memory so even though you're outside the building, the building TEM would apply to the RFP shot; And since a FFMO cannot exist simultaneously with the application of a TEM it (FFMO) is not taken into account at all.
