@Noneshallpass I think the roundels were originally just a fun extra flavor for using under your Panzer Grenadiers in the standard game (i.e. before they created this expansion). So it was, and is, fun to have the insignia’s included on even just for flair! But when using the Expansion I suppose they become worthless as a Global War piece since the standard game Panzer Grenadier rules are replaced. But yeah, I do think that’s the explanation on why you received them with the Expansion.
Good point on the wording. I could certainly be wrong given that wording that I clearly overlooked. My gut says that might be an error, in wording, but that’s obviously not official haha. I’d say if there’s one big flaw in the rules over time, it’s been consistency in wording and also clarification at times, so I do think that could be it.
I guess you could, as a sort of “house rule”, decide that the January 1943 placement rules can be changed to putting the roundels under mechanized infantry, and then the July 1943 would be upgrading those mechanized infantry to medium armor? May be too much of a stretch though.
