Workers and Peasants Supplement (2010) - What is East Front Deluxe

[nbisada]

In the July 2010 edition of Workers and Peasants: The Red Army At War - 1941 (I happened to have a copy with the upside-down and backwards cover), there is mention of Eastern Front Deluxe in several of the scenarios, which specifically limit Soviet Leaders, Pieces and/or Boards to EF Deluxe, sometimes with Leaders found in W&P. Were the Leaders and Pieces different in the boxed Eastern Front with a tank on the cover compared to the slipcover EF with cavalry on the cover? Is the latter EF Deluxe (and should this be Supplement Errata)?

I know of the Artic [sic] Front Deluxe supplement noted in AGC Scenario 1

Army Group Center:
Scenario 1 - Leaders from EF Deluxe
Scenario 2 - Leaders from EF Deluxe
Scenario 5 - Pieces from EF Deluxe
Scenario 6 - Boards and Pieces from EF Deluxe

Army Group South, :
Scenario 1 - Leaders from EF Deluxe

Thank you
