What is Milsim?
Milsim (Military Simulation) is a style of tactical gaming that replicates real-world military operations, tactics, and communication. Unlike casual multiplayer shooters, milsim units operate with authentic military structure — complete with ranks, chain of command, standard operating procedures, and realistic rules of engagement.
In Arma Reforger, milsim units like the 506th Infantry Regiment take this to the next level with structured training programs, weekly operations, and a professional environment that mirrors actual military experiences.

Why Join a Milsim Unit?
Joining a milsim unit transforms your gaming experience from random matches into coordinated military operations with a dedicated team. You'll develop real teamwork skills, learn tactical communication, and form lasting friendships with like-minded players.
Many milsim units include active duty military personnel and veterans who bring authentic expertise to the experience. The 506th Infantry Regiment was founded by former members of the 15th MEU(SOC) Realism Unit, and many current members are veterans and active duty military from around the world.
The 506th Infantry Regiment — Arma Reforger's Premier Milsim Unit
Founded in November 2014, the 506th Infantry Regiment Realism Unit is one of the longest-running and most respected milsim communities in the Arma ecosystem. With over 4,900 registered members and 190,000+ forum posts, we've built a thriving community dedicated to authentic military simulation.

We fully transitioned to Arma Reforger in July 2024, making us one of the first established milsim units to commit to the platform.
