An ArmA 3 Military Simulation Community

Who are we?


Australian Combined Operations MilSim (ACOM) is an ArmA 3 Military simulation unit which aims to produce not only realistic training, deployments and atmosphere but also a welcoming and enjoyable community.

The members of ACOM, conduct and take part in training and operations which are inspired by the real life version of this unit. While doing so, we also do our best to make sure that all members feel comfortable, safe and accounted for. If you are interested in taking up arms with your fellow larrikin Aussies, within an organised militaristic unit and also a chance to make new friends then ACOM is for you.
