I only wonder about availability of ammunition: AFAIK, Ukraine was critically short on artillery ammunition for years (thanks to the MOD who didn't buy any). Sure, over the last 1-1,5 years, it imported a lot, and even more is literally flowing into Ukraine, the last two months. But, if that's enough and of calibre 203mm.... I doubt that, simply because 2S7 is a rare appearance.
