The only source cited is a blog which cites a blog + raw acquisition numbers from government data, none of which contain ANY reference to "guided missiles" or "artillery" as the original substack claims.
As best I can tell, this claim was just kind of made up, then referenced by a blog, and now by the daily beast. We're like 3 days out from NYT writing this and referencing this daily beast article.
Fuck this administration for all the illegal and inhuman shit they're doing, but I'm almost certain this is just made up. They definitely have spent a shitload of money on weapons and equipment (bad) but theres no proof they've bought explosives and chemical weapons (beyond pepper spray)
