The cans in the market suddenly stopped having labels. I don't think it was because they ran out of paper.
Initially after the disaster, the military and the liquidators used equipment during the construction of the sarcophagus, the evacuation of Pripyat and the burial of other hazardous waste that would later be dumped in pits and left to radioactively rot. This included BTR armoured personnel carriers that were used to bring in soldiers, helicopters that were flown over the reactor while it was being buried, and other military vehicles.
Buryakovka field is one of several waste-burial sites where radioactive hardware is either buried or waiting to be buried. Along with military vehicles, there is also the tank that the liquidators used to pour the sarcophagus (it is now encased in lead) and a long column of fire engines that arrived to try and extinguish the blaze.
