"Regular servicemen of the American army, as well as the armies of a number of European countries are constantly working ‘on the ground,’ including assisting in the calculations of the gun complexes, US-made HIMARS multiple launch rocket systems, helping to use them in the military hostilities," Lavrov told the Russian Rossiya 1 broadcaster.
The minister emphasized that Moscow does not have a 100% proof of this information, but the evidence was multiplying and the West was starting to realize that they are going a little bit further than they intended.
On February 24, Russia began a special military operation in Ukraine responding to calls for help from the breakaway republics of Donetsk and Lugansk amid intensified aggression of the Kiev regime. Western countries responded by imposing comprehensive sanctions against Moscow while also ramping up their military support for Kiev. In late September, referendums on joining Russia were held in the republics of Donetsk and Lugansk and parts of Ukraine controlled by the Russian forces. All these territories were integrated within Russia based on the results of the referendums.
