Thanks for clarifying this, Andy. Personally, I had forgotten that the 2S7 is X3 in the original OOB.
So basically, the difference between US and Russian heavy SPHs is mainly in frequency of use. The 2S7 can get the
real loadout because it cannot be used by the IA, while the M-110 can be used autonomously by the IA player.
Keep in mind that the M-110 is standard issue in US divisions, while the 2S7 is only used at army levels and above, right?
I'm of the opinion that the Russian OOB could do with a separate class for heavy SPHs as well (2S5, 2S7 and certainly the 2S4), but that's just a suggestion.
