На Гравитиме про ИС-3 такое вычитал:
Что то в наших источниках такого не нашел. Откуда у буржуев такие дровишки?I read one famous French historian Dumas de Friniko and according to his researches at least THREE JS-3 took part in the operation to intercept German Kampfgruppe, which tried to get to the American area and surrender Wink
This operation had place in Austria, May 1945.
