Battlesim.com runs monthly WWII games the last Sunday of each month. The next one is March 25 and will be a Brecourt Manor scenario. We'd love to get more people in WWII gear! Our last major event had 55 WWII airsofters from around the world (our furtherest was from England).
We are also planning a D-Day+3 for June 8,9,10.
