I’m not sure that’s generally true. The ATACMS that were used operationally were the shorter range versions (M39), because these have more submunitions, which maximised the destructive effect on the airfields in Berdyanks and Luhansk. But I think longer-range versions (M39A1 and M57) will likely also be provided, as they reach their end-of-life, as Jake Broe explains.
That article is also six weeks old and talks about a decision to be taken “in two weeks”. Which I think was still “no” at that time. Also, the “relatively easy” range reduction was just a theoretical answer, and German thoroughness means that it may take a few months, anyway.
We’ll see what these great news from Germany are that Kuleba hinted at yesterday.
