The20/25TP (dwudziestotonowy polski/dwudziestopięciotonowy polski; "20-tonne Polish/25-tonne Polish") was a Polishmedium tank concept that was never built. There were three projects designed by KSUS andBBTBr.Panc. andPZInż which even managed to build a wooden model of it. The name 20/25TP is not official; it was created by the authorJanusz Magnuski analogously to nomenclature used for other Polish tanks of that period.
