".the Polish army has 900 modern tanks including German made Leopard IIs to reteach the Russians not to mess with Poland. "
Isn't that about 900 tanks total?
Many older T-72's from the Russians?
About 250 Leopards. The T-72's are completely rebuilt with Polish engines and trannies, new turrets, NATO standard 120mm or 105mm guns, laser sights, etc.
Nothing to look down on compared to Russian equipment.
