A joint Mongolian-Russian military archaeological expedition has conducted its first underwater dive in Buir Lake and carried out a third large-scale excavation at sites associated with the Battles of Khalkhiin Gol.

The excavation uncovered the remains of more than 40 individuals, along with a range of historical artifacts used by soldiers.

Russian experts participated in the expedition, and the unearthed items are being examined in a temporary field laboratory. Specialists are conducting detailed analyses to identify the individuals and document the purpose and origin of the artifacts. Among the findings were materials that enabled researchers to identify six servicemen by name, as well as a letter written by a Russian soldier to his wife.

Colonel Togmidduumii T., Head of the Training Department of the Land Forces Command, led the Mongolian side of the expedition. Personnel from the National Defense University of Mongolia, the Defense Research Institute, the Central Defense Archive, the Mongolian Military Museum, Armed Forces Units 284 and 327, the General Authority for  Border Protection, the National Emergency Management Agency, and the National Forensic Agency took part.

The Russian delegation included representatives of the Defense Attaché Office of the Russian Embassy, along with professional experts and divers.

The expedition follows agreements reached by the Heads of State of Mongolia and Russia. Earlier exploration missions were conducted in May and September of last year.
