You will be able to manage your server sending commands remotely through the RCON just like if you were typing on the server console. This includes any command supported by the game server. After the command is typed you will see the server response, for example if you have typed "players" in an Arma 3 server you would receive all the information regarding the players connected. The app supports any command supported by the game server. You will also be able to kick, ban and send messages to the connected users.
