NATO troops are already in Ukraine for arms control

NATO troops are already in Ukraine for arms control, intelligence operations, and training, according to El Pais. The agency has interviewed many military sources from Ukraine and the EU over more than two years of war, and they all agree that no NATO army has taken part in ground combat. But they also agree that they have informants on the ground who provide information about the situation on the frontline, determine the effectiveness of the weapons being supplied and possible problems in their use, and identify possible cases of corruption in the delivery of aid.
