Pro-Russian Telegram channels and media write about this. The Russian army is allegedly opposed not by the Armed Forces, but by foreigners, "NATO armies", "battalions of Poles", etc. According to Russian intelligence, the Ukrainian army is currently filled with foreign mercenaries by 30%, and soon the number will exceed 50%. That's when the message will allegedly be made that NATO troops are fighting in Ukraine. It is a fake.

According to the President of Ukraine, Volodymyr Zelenskyy, about 700,000 Ukrainian soldiers are resisting Russia's invasion of Ukraine. The number of foreign volunteers is estimated from several hundred to several thousand people and can`t be "half" of the Armed Forces.

In August 2022, the General Staff of the Armed Forces reported that no more than 100 foreign servicemen are serving in the Ukrainian army under contract. As StopFake writes, in March 2022, about 20,000 volunteers applied to participate in the International Legion of Terror Defense of Ukraine. The legion includes fighters from all continents. The largest number of representatives are from the USA, Great Britain, Poland, the Baltic countries, Canada, Norway, Finland, and Denmark. In general, it is 70–80% of foreign volunteers. According to the Embassy of Ukraine in the USA, more than three thousand Americans applied to join the Legion. However, the final number of foreigners is not announced by the military command for security reasons. The indicated numbers are only applications, and it is unknown how many of those who expressed a desire to go to the front actually went to fight.

Russian propaganda spreads fakes that the NATO army is allegedly opposing them in Ukraine to justify the failures of their army for the Russians. Moreover, the agitprop said that allegedly the Ukrainian military can`t reach the level of military training according to NATO standards. Furthermore, the successful counteroffensive of the Armed Forces is due to the Pentagon's direct participation in the development of the plan.
