Between January and March 2020, US Army Europe deployed approximately 6,000 military personnel from the United States to Europe. It moved some 9,000 vehicles and pieces of equipment, many from prepositioned stock locations in Europe, and around 3,000 pieces of equipment across the Atlantic. To give an idea, this is the third-largest military exercise in Europe since the Cold War. In coordination with Allies and partners, US Army Europe also moved soldiers and equipment from multiple European ports and airports to training areas in Germany and Poland.

On September 4, the American B-52s entered the airspace of Ukraine for the first time in history, where they made a long flight along the borders of the Crimean peninsula, thus demonstrating an unprecedented disregard and aggressive behavior towards Moscow.[10]
On Sep. 25, two U.S. bombers staged a mock attack run on Russia’s territory in Eastern Europe. The flight path allowed the bombers effectively to fly a circle around Kaliningrad, a Russian exclave on the Baltic between Poland and Lithuania. The simulated raid on the Kaliningrad region was a test case of destroying Russian air defense systems located in the region.[11]
Altogether, in August-September 2020, American nuclear weapons carriers flew at least 18 times to Russia's northern, western and southern borders during the operation, which is an unprecedented event since the end of the Cold War.[12]
