New England's Biggest Field
Advanced Action Milsim brings premium special events to a 400-acre Granville field, the biggest field in New England. The scale supports deep tactical scenarios, large player groups, and multi-day play without sacrificing clear movement around the site.
Built for Immersive Operations
Dense woods, open ground, strategic positions, and two designated helicopter pads give event organizers room for detailed missions and coordinated team play. Marked roads and trails make the large field easier to navigate while preserving the scale and challenge that serious milsim players expect.
Plan for the Full Event
Granville opens for scheduled special events. The site includes a six-acre parking area and portable toilets. Camping and fire pits may be available for an additional fee, making it possible to keep the experience going across multiple days.
Location: 553 West Hartland Road, Granville, MA 01034
Advanced Action Milsim events are hosted at Moose Valley Recreational Area, a separate Granville business and venue.
