EDIT My mistake: This thread was for SK and we were not play g SK when the incident described below happened. Sorry for the confusion.
OK, what about this situation? Finnish 1/2 squad w/ 'Schreck burning wrecks a Russian tank at range 0 (was HIP and tank entered hex). 1/2 squad is marked First Fire. Later, in same movement phase, another Russian tank rolls up to range 1 hex away and stops.
In Defensive Fire Phase, may the 1/2 squad fire the 'schreck again against an adjacent tank? I believe the answer is yes. But, I also believe it is open to interpretation. When it happened, we played it such that there was no additional 'schreck shot in the Def Fire Phase.
The 'schreck is a SW. In Def Fire Phase infantry may fire inherent and SW as area fire. The 'schreck is ordnance. I believe 1/2 squad may fire again w/ a penalty (NRBH but I want to say Case D. This would apply b/c the 1/2 sqd would fire its Infantry firepower as 1/2 for firing as defensive fire while marked as first fired. It would be same effect as area fire penalty.)
