Arma Units

I am looking for active units to put up here, If you want to feature your Unit here for no cost, hit me up (Discount Ninja) on Discord.

One of the best and worst parts of Arma is multiplayer, but for that, you’ll need to join a Unit. Joining a Unit generally requires application and training. You can end up with a tight group of friends or have conflicts. It can be hard to find an Arma Unit, so I’m compiling a list, enjoy.

Before we look at the Units, I’ll go over some major terms a lot of Units used.

Milsim Types

There is usually a strict hierarchy of ranks. You usually find a lot of privates and corporals in a Milsim unit. Very top-down, high-level organization. There’s formal training and qualifications on equipment
This is usually an authentic recreation of a real-life unit. You often find Active Military and Veterans in these groups.

This type of unit usually goes for science fiction or historical settings. Popular Examples are; Halo Units, Star Wars, WWII, Vietnam, and Warhammer. The focus is on the setting.
Usually a formal structure
Training can be non-existent or formal

This type of unit focuses on fun and gameplay. Ranks are very simplified. No loadout limits, you’ll often find someone that blows up friendly assets for shits and giggles. These are usually an open community.


If you want your Unit to appear in this list, get in touch with “Discount Ninja”. Either on Steam or Discord, the easiest way may be Discord.
