Poland would make quick work of Wagner. They have not fucked around in making their army one of the best in Europe in combined arms warfare. They’ve also updated their most of their materiel to Western gear (or are producing their own that is equal to Western gear) that we now know is dramatically superior to the old Soviet//Russian gear. They’ve been in on practically every peacekeeping mission across the world for the last 25 years, seasoning their officers with combat experience. They are far more competent than Wagner, to put it briefly.
