The problem here Andy is he has switched from discussing the unit that exists IN THE GAME to "reality" and what he is saying is in "reality" the 2S7 Pion was introduced sometime in 1976 and carried 4 shells onboard and the upgraded 2S7M Malka ( which we don't currently have in the game ) was issued with 8 shells on board.
When someone says "In game error" then starts discussing "reality" it gets confusing. That's we introduced a standardized error reporting procedure detailed at the top of this section.
We will look into the issue when we start work in the fall though I'm sure no matter what we do someone will think it should have been done differently
