Steam is the ideal choice to acquire the Arma 3 server, offering two methods for obtaining it: through steamcmd or Steam Command-Line. If you’re working on a remote server, the command line is a suitable option.If you plan to install the server on your home computer, you can simply install it through Steam. Although it may not be listed in the game menu, you can find it in the Library under “GAMES AND SOFTWARE” in the drop-down menu. Look for “tools,” and you will find the Arma 3 Server there. After installing it, you can immediately launch the server.
