On a street in the village of Mara Lohan, 3 km north of Kharkov in eastern Kharkov Oblast, recaptured by Ukrainian forces on March 29, 2022, Ukrainian soldiers pass by the bodies of two Russian soldiers lying on the ground at the entrance to a hut.

   Ukrainian troops recaptured the village of Mara Roman, 3 km north of Kharkov in eastern Kharkov Oblast, on March 29, 2022. The next day, on a street in the village of Mara Roman, Ukrainian soldiers passed by the bodies of two Russian soldiers lying on the ground at the entrance to a hut. They searched in front of the bodies of the murdered Russian soldiers. According to the Ukrainian policeman, one of the two was dressed in plain clothes over khaki-colored trousers. The Russian soldier was dressed in a blood-soaked military uniform, and his body appeared in a ditch where shrapnel was flying and through a doorway. More than a dozen corpses of Russian soldiers were strewn across fields and houses in the eastern suburbs of Kharkov on March 29. The battle to free Mara Roman lasted almost three days. Russian troops were surrounded by Ukrainian forces on the eastern front around Kharkov, especially Russian soldiers trapped in the surrounding village of Mara Logan.

The Russian military cremated the bodies of soldiers in the invasion of Ukraine to conceal their losses and avoid compensating their families. Russian soldiers were declared missing, other soldiers' corpses were buried in unmarked graves, and other corpses were disposed of in mobile crematoriums. In response to the growing military losses from the invasion of Ukraine, they sought ways to conceal the original number of casualties. One of the tactics used by the Russians to conceal their losses was the cremation of corpses. Special mobile crematoria were brought into the occupied territories. The mobile crematoria were set up in front-line areas, and the pungent stench wafted far and wide. To avoid surveillance, the Russians set up the crematorium on the right bank of the Dnipro River. The distinctive smell of burning flesh leaked into the surrounding area.

　The Ukrainian military used facial recognition to identify Russian soldiers killed in action and sent their photos to their relatives. It has already recognized more than 8,600 Russians and contacted the families of 582 Russian soldiers killed in action using the facial recognition method, the Washington Post reported. Russian troops also destroyed the bodies of their casualties in the Chechen conflict. There were reports of Russian troops dropping the bodies of dead Russian soldiers from helicopters into canyons. They avoided wasting time and resources in transporting the bodies. The Russian military recreated mercenaries among Middle Eastern youth, Central Asians, and minorities living on the Russian frontier, as well as in Syrian and African countries.

    The number of human casualties of Russian soldiers was much higher from the war in Ukraine's Donetsk Oblast. Some bodies were cremated and others buried in unmarked graves. The lower the number of casualties, the higher the rank of the commander. Losses were concealed in order not to lower the morale of the troops. The Ukrainian military announced on August 11, 2022, that some 43,000 Russian soldiers had already died in the invasion of Ukraine. Only twice did the Russian military officially announce the number of dead, the last time on March 25, 2022, when the figure was only 1,351. In the Donetsk and Luhansk People's Republics occupied by Russian troops, the local KGB oversaw modest funerals. Ambulances began collecting the bodies in plastic bags, one covered with bed covers near a bus, the other two at the entrance to a hut illegally occupied by Russian soldiers for several weeks, on December 15, 2022, during the Russian invasion of Ukraine, liberating the outskirts of Kupiansk, Kharkov Oblast, and the Ukraine Military soldiers unloaded the bodies of Russian soldiers found in the village of Petropavlivka in plastic bags.
