Based on his name, I suspect Mihail Titov was really Russian or at least of Russian descent. Anyway, it seems he often plays Russians or Germans.
He has a great role as a Russian general in TotÚ e Peppino divisi a Berlino
He is listed on the film's IMDb page under the slightly "Italianized" name Michele Titov
, but he is not credited in the actual film.
And here he is in a fairly large role as a German colonel in Testa di sbarco per otto implacabili
Once again he was uncredited, but I have found this Italian poster for the film and here you can see that he is credited as Michele Titov:
