Looks like a fun airsoft milsim game that took place in Poland. Combative Airsoft has the video to show us what happened... "Awesome Milsim game from a few weeks ago. The location we played at was a chemical and ammunition plant/factory in central Poland. It was active before, during, and for a short while after World War 2 and fell under the control of the Nazi's during the war and by the Soviet Union during its reign.
