Before I explain my opinion I have to explain number of tanks into polish army.
As tanks were counted here vehicles called "Tankietka". It was small (2 people staff) vehicle with heavy machine gun - generally worse that armoured car.
Wow thats fascinating a tank armed only with machine guns , you mean just like the Germans and Russians had ,and the Brits and Americans French Italians Finns Japanese . But of course all those other armies didn't count little machine gun armed tanks as tanks they called them tanks instead .
Now of course that would just be a little comparrison , for another comparrison you could take some more similar tanks , or even identical ones say perhaps Polish and Finnish ones (though of course not little toy tanks but real ones with guns that go bang) The Finns managed to get most of theirs into action despite bad weather , the Poles kept them in reserve then drove them to Romania .
