We have been using Teamspeak 3 for comms. The Server info is on the first page. You should see a screen like this though. Click Connections and a window will pop up. Plug in the Server info and Password and your Nickname. Once you do that and Connect it should look like this; We're at the bottom do click War Thunder and you should be GTG. Oh and once you connect, you might want to add the Server info to your Bookmarks so it's saved. Otherwise if you switch TS3 servers you'll have to enter it back in each time. If it's your only TS3 server then you don't really have to as it will remember your info from the last time you connected. So first go to MENU and click Squadron. Then add everyone as a friend. It should look like this; Once that's done you can then close that window. Go to the People Icon next to MENU and scroll down to Friends. If someone's in Green they are online. You can Right-Click their name and Invite them to a game. A new CHAT window will open up and those who accepted the invite will be listed. When the little icon next to their name turns green they are ready to go and you can then start the game. The tier of the mission will be dependent on the highest lvl plane in the squadron. So if you only have tier 2-3 and someone else has 4-5, you will play at tier 4-5.
