So what is the back story to the "modern Prussian" campaign?
A modern rebirth of the state of Prussia from Kalingrad, as a Heinleinist country, a buffer state sponsored by Russia. Russia thought that Prussia would serve as another pro-Russian voice in Europe. Prussian troops fight in the former Soviet break-away region of Karakistan. The Prussian Army Afrika Brigade has been sent to assist a friendly Heinleinstic faction in the civil war torn African state of Mafeking.
