Thanks for the perfectly built T-72B3 model. But something still puzzles me. The buttons to the left of the TPD-K1 sight are only eye-candy, even though hovering the mouse over them will make the icon indicate that they are clickable. So is it a bug or just what it is in a real vehicle? I know in the B3 version, the TPD-K1 is only retained as a backup to the Sosna-U sight with many functions, like laser ranging, lead calculation etc, stripped. And one possible bug reporting. The type code of the sighting complex in the Gunner's handle reads 1A40-1, but I guess it should be 1A40-4. And the SB wiki manual for B3 says that rounds can not be unloaded once loaded into the main gun, but I think it's untrue. I refered sources from Tankograd/Soviet Armor blog. Not sure whether I post in the right place. But thanks in advance.
