Hello Pulverisor:
I'm a 50+ year wargamer, surfed on in looking for 'Westfront PanzerBlitz Variant from Spartan #1 mag from 40+ years back.
There's a whole line of games that grew out of Panzerblitz. The designer Jim Dunnigan (former US Army Artillery 2nd D), ran SPI=Simulations Publications Inc. They produced the following,all based on PB with some modifications. If you haven't joined BoardGameGeek, i'd suggest you try it.
Red Star/White Star cold war porting of PB
