Does the 2nd PZ have to make a 1st attack to be able to make the
second attack given by the card...
Or can the 2nd Pz just move across the board...and after all other
combats are done...then make an attack (which could be devastating)??
One has to think that you cannot make a "second" attack without making a "first" attack.
I think your second suggestion would be expressed as "an attack subsequent to all others".
