NationStates

Are these symbols permitted in NationStates to be used on a flag/custom banner?

Sturmabteilung Embelem/brand (The one with the S and A, not the swastika based one)
Iron Cross
Balkenkreuz
The Saying: "Gott Mit Uns!" (God with us)
Celtic Cross (The Christian one, not the Neo-Nazi cross)
The Eagle Crest Without Swastika (Seen on Wehrmacht Helmets)
The Panzer Lehr embelem
Prussian Eagle
Pour Le Merit
Totnkopf (Lieb Hussaren Version, not Schutzstaffel)

Thank you for your help!
