Question:
What strength Pz XX can detach the Pz IV Bn, and does such a Division become PzGren just as if it detached a Panther Bn? Should there be a (-2 PzG) marker to reflect this detachment?
Answer:
The single Pz IV detachment in the game enters play already detached. The SF rules allow you to operate it independently or to attach it to a panzer division. Thus the question about what type of panzer XX it can detach from is immaterial, because the game does not allow you to do this. The Pz IV detachment operates in a similar manner as a Panther Bn (again per the SF rules), thus a 16-10 Pz XX with a 2-1-10 Panther Bn attached would be treated as a 18-10 Pz XX.
