U.S. Army and NATO plan four-country eastern flank command drill with 4,000 personnel and more than 2.2 million simulated forces

The US Army and NATO plan a four-country command-post exercise involving about 4,000 participants, split roughly evenly between American and multinational personnel. Headquarters from US Army Europe and Africa, NATO LANDCOM, V Corps, and several European corps will use a scenario representing more than 2.2 million simulated forces to test theater-level command, data exchange, and eastern-flank reinforcement. The 2.2 million figure describes entities in the simulation, not troops physically assembling for the drill. The design emphasizes decision-making across several headquarters rather than a mass physical deployment of millions of soldiers.
