Yeah, I remember finding out this, about the second backpack I opened of the ones that you need to open to change batteries.
I thought some kind of holy grail was going to be discovered
.What I think is more fun & interesting, is the fact that in some countries the voices of the talking commanders was translated. So, you have Overkill speaking spanish for example, which is all kinds of cool. What I don't know is if other countries had them translated too, such as France, or Italy, or Germany, which at least had filecards and blisters in their languages, at least for some time.
