A3 Milsim (A3M) is, primarily, a non-profit ArmA 3 mod and content production company tailored for the MilSim and realism communities within the greater ArmA 3 community. Our flagship product, A3M PMC Simulator, has a playerbase of small communities numbering in the thousands. Despite calling ourselves a "community", no actual milsim community exists here at this time. The extent of the community at A3M is comprised of volunteer developers involved in A3M projects.

Our MilSim content offers niche crowds of active duty and prior service military personnel, law enforcement, private security personnel, and realism enthusiasts an enjoyable, hyper-realistic and often quite complex experience not found anywhere else in the world.
