Catching up with YouTube and saw a comment about op fire.
Suggestion
If a unit only spends one hex in LoS of a unit taking Op Fire then it should be allowed to complete its action in that hex before being subject to the fire so that a move/fire or move/unload is not subject to fire until after the fire or unload. The unit moving has planned its action and won't be hanging about whereas the OP fire unit will need to asses and then fire.
