I think that there is a deficiency, if not a problem, with the Equipment Cards. The backs of the cards can indicate if equipment is "Character-Specific Equipment", i.e. equipment that is "specific to a certain character" (like the Stosstruppen's Infernal Sustenance), or is "General Bonus Token Equipment", i.e. equipment that is "not specific to a certain character".
The problem is that most of the cards in this latter category ARE specific to a Faction, like the Reich's Helm of Diomedes or the Union's Presidential Unit Citation, but in most cases nothing on the card, front or back, indicates this. (A few cards mention the Faction restriction in the text.) The cards were meant to replace having to shuffle numerous rules books to deal with the equipment, but without this information, you'll still need the rules to know what item goes with what Faction.
Perhaps future editions of these cards could have Faction-specific backs?
