Col. Carl Johnson from the 139th Airlift Wing. He said teams can contact him to register.<br /> <br /> Johnson said veteran team members will welcome old rivalries before the first pitch is thrown, and then they will dig in, swinging.<br /> <br /> More than 500 players will compete, to include Guard members and their families as well as players from other services.
