I fixed the tower, now it rotates (F, H), but cannot go up / down. A 4-speed gearbox was added, like on the real T-80U. The engine is adjusted, now it puts out 60 km / h in 4th gear (the transmission is manual, to shift it, first press Q to enable manual shift, then X to shift to the next gear and Z to shift to the previous one) . Realistic turbine engine sounds and a realistic gunshot sound were made.

✅15 configurations.
✅ There is an animation of caterpillars, they rotate and have a collision.
✅ The tower rotates (F, H). The implement can be raised/lowered (T,G).
✅ The gun can shoot (Y).
✅Working machine gun can shoot (Home), rise, fall (PgUp, PgDN)
✅ Working headlights, rear lights.
✅ There is a smoke grenade (End).

❗Disadvantages of modification : No PBR textures, pixels are visible on textures close up. Anti-cumulative screens cannot swing, bend. Also, there is no separate rubber texture for them. The caterpillars may curve strangely, which is not realistic. And also the caterpillars do not go underground much.

What's in the new version:
Added new rollers and tracks (thanks to Artistterrymartin), now they are more rounded. A bug with the lack of an engine was also fixed.
