In the world of airsoft, there are events that players eagerly anticipate, and American Milsim’s (AMS) Northern Front series is definitely one of them. On June 6–7, 2026, the small town of Mauston, Wisconsin, will once again become the stage for a large-scale milsim game at Action Sports Wisconsin, continuing the storyline of a fictional civil war between two powerful factions: the Coalition of Sovereign Territories (COST) and the United Federal States (UFS).
American Milsim is one of the largest milsim airsoft event organizers in the United States, known for its attention to detail, well-crafted scenarios, and strict dress codes for each faction. AMS games are famous for their high level of immersion — it’s not just about accuracy, but also about operating as part of a unit, following the chain of command, and staying true to the operation’s lore. The Northern Front series is one of AMS’s flagship events, regularly drawing hundreds of players from across the country.
The events of Northern Front 6 take place two years after the fierce battles in Mauston, which was once the epicenter of the COST-UFS conflict. After both sides suffered heavy losses, the region fell quiet. However, according to COST intelligence, the situation may be about to change dramatically.
Previously, local units of the Civilian Defense Force (CDF) supported the Coalition, helping maintain influence in the region. But after the CDF abruptly withdrew, a power vacuum emerged that federal forces exploited. Now, two years later, reports indicate that several CDF groups have been approached with bribes and offers of military equipment in exchange for helping push back into Mauston and holding the city for the UFS. COST command is seriously concerned: if the CDF switches sides, it could give federal forces a foothold in a strategically vital region.
Players will determine the outcome of this standoff. Can COST maintain the loyalty of the local militia? Or will the UFS sway them and seize Mauston? The answers will be found on the battlefield.
Northern Front 6 is a two-day event with overnight camping. Organizers set a player cap, and importantly, no walk-ons were allowed — registration was strictly advance-only. Pre-orders for gear through official partner Amped Airsoft were accepted until June 2, allowing players to pick up their equipment on-site.
The participation fee was $155 (plus fees and tax). This includes a commemorative event PVC patch, an AMS Event Veteran PVC patch, an AO map, and a ticket for the end-of-game raffle.
Important rule: all American Milsim events are BIO BBs only — biodegradable BBs are mandatory across all AMS games.
As in previous games in the series, participants are divided into two opposing sides:
CDF (Civilian Defense Force)
Players on this faction must look like civilian militia. Solid colors, denim, flannel, grey, and other colors are allowed, but camouflage and tan are strictly prohibited. No camo pants or tops — civilian attire only.
UFS (United Federal States)
Federal forces, on the other hand, must be equipped in appropriate camouflage: Multicam, Desert MARPAT, AOR1, Multicam Arid, and other desert patterns. Headgear must match the base camouflage color (tan tones).
American Milsim isn’t just about “shooting in the woods.” It’s a full-scale combat simulator with tactical objectives, teamwork, and a deep storyline. Northern Front 6 promises to be one of the standout events of summer 2026 on the U.S. airsoft calendar. Even if you missed registration this time, keep an eye on AMS announcements — the Northern Front series will surely return with a new chapter.
