Tuhia he tomokanga mō tēnei wāhanga - I ngā tīmatanga o te Pakanga Tuarua o te Ao, i uru atu ngā kōwae eke hoiho o te Ope Taua o Mongolia ki te Pakanga o Khalkhin Gol ki ngā ope ā Iapani. Ko nga ope Soviet i raro i te whakahau a Georgy Zhukov, me nga ope Mongolian, i hinga i te ope ono o Hapanihi me te mutunga o nga Pakanga Rohe o Soviet-Japanese. Whai muri i te Soviet-Japanese Neutrality Pact o 1941, i noho a Mongolia ki te taha o te pakanga, engari ko tona ahuatanga matawhenua i kii ko te whenua he waahi i waenga i nga ope a Iapani me te Soviet Union. Hei taapiri ki te pupuri i te 10% o te taupori i raro i nga patu, i whakawhiwhia e Mongolia te haurua miriona hoiho whakangungu hei whakamahi ma te Ope Taua o Soviet. Hei taapiri, ko etahi waahanga eke hoiho o te Ope Taua o Mongolia i tautoko i te ope a Soviet i te taha hauauru o te Manchu Strategic Offensive Operation
i te tau 1945. I noho rātau hei wāhanga o te Rōpū Miihini o Mongol Soviet i raro i te whakahau a I. A. Pliyev
