What does Russia do with Soyuz that returns to Kazakhstan

Hi, Today I read about Gregory Olsen and the other astronauts landing
in Kazakhstan and I thought to mysel, "what does the Russian space
agency do with them once they land?" Do they load them on a truck and
cart them back to mission control? Do they remove any critical
equipment and then leave it there for nomadic tribesement to find and
look at? Do they remvoe any critical equipment and then blow it up? I
figure it's probably a ways from the nearest big city so I was just
wondering.
Thanks!
