Its Czechoslovak tank brigade. Tank commander clearly says at 21:20 "Direction Czechoslovakia! At 22:00 they enter borders to Slovakia, symbol on the table is the coat of arms of the Slovak Republic which consists of a red (gules) shield, in early Gothic style, charged with a silver (argent) double cross standing on the middle peak of a dark blue mountain consisting of three peaks. Once we were two nations united in one state - Czechoslovakia." Name on the burning tank hit by panzerfaust is Jánošík - national hero, similar to Robin Hood. At 23:00 there is Czechoslovak flag on the wooden church. After break of Czechoslovakia this is now known as Czech flag. My favorite movie from childhood.
