Funny, I was following this subject on FR and did not see any “reports” about Poland sending regular troops to Ukraine. Would you mind sharing them, please?
IMO all the Belarusians could do is dump artillery on POL positions provoking cross-border hostilities to distract from RUS offensive failure.
The POLs are smart and capable. They are old-school direct command leadership structure, more akin to Prussians than anything else imo. And they promote those leaders so it is the prevailing élan of their Army.
They will know to dig in. If they choose to go on offensive they could take Minsk in days and Moscow in 2 weeks. But they will follow NATO leadership, use restraint and suffer unnecessary casualties.
