I may be 100% wrong, but I feel like I remember hearing somewhere that America made a lot of artillery (this may be wrong, maybe during ww1?) and I was wondering if tanks made by America (or possibly other allied nations producing weapons at the time) that were supposed to be used for the war effort were used during the invasion of Poland by Soviet Union? (I may be way off on what I said/facts may be wrong but I was just wondering) 😁
To clarify - are you talking about the Soviet invasion of Poland in 1939? Because in that case, no, no Allied equipment would have been used by the Soviets. The American Lend-Lease policy of sending arms and supplies to Allied nations did not begin until 1941, and the USSR did not receive Lend-Lease shipments until October of that year, after the Nazi invasion.
If you're talking about the Soviet offensives into Poland in 1944, then yes, American tanks and equipment were used heavily. Operation Bagration, for instance, benefited greatly from the impact of American supply trucks on Soviet logistics.
