I know Lieutenant Colonel Alex Vindman from a combined US-Russian exercise called Atlas Vision 13 in Grafenwoher, Germany. He worked with the Russian Embassy and I was assigned to the Joint Multinational Training Command within US Army Europe. Vindman worked coordination with the Russian 15th Peacekeeping Brigade, and I was in charge of all Simulations planning, as well as assisting the US Army Europe Lead Planner as the Senior Military Planner.
