It would appear that there were four Ukrainian Fronts (armies). The 1st Ukrainian Front appears to have been involved with Berlin near the end. So I am guessing my Vishnjakov was with them (of course I do not know that he was with a Ukrainian Front - how would have Ukrainian been recruited?). Did the Ukrainian Front have any tank units?However the 1st was disbanded in June 1945. So I am wondering how that happened and where the sections went. We know he was with the Red army in Estonia at the beginning of 1947 and probably from at least 1946.
