In game:

To connect to AWACS, you need to be inside of an aircraft, use the scroll well action to open the dialog, in ACE use the plane interaction and select: "Connect to AWACS".

Then you need select what AWACS you will connect to, in that dialog you will have other options as well, those are:

Convert to imperial: The AWACS will give the range and altitude in imperial unit.

Enable Auto report: The AWACS will automatically report on targets that show on radar, and also a quick picture from your position.

Delete Markers: Will delete the Home Plate and BullsEye marker on the map

To Make Markers for the picture request and require Home plate just make a marker on the map named "AWACSHome"(for Home Plate) or "AWACSbulls" (for Bullseye)

After connecting to an AWACS, you will have new actions. They are:

Vector to bullseye
The AWACS will provide the player with a bearing and range to bullseye.
Vector to home plate
The AWACS will provide the player with a bearing and range from bullseye to their home airfield.
Vector to tanker
The AWACS will provide the player with a bearing and range from player to the tanker
Request BOGEY DOPE
The AWACS will provide the player a BRAA call to the closest airborne threat.
Request PICTURE
The AWACS will provide the player with BRA calls for each group from bullseye.
DECLARE.
The AWACS will identify friend or foe of a radar looked target.

You can use custom callsigns and the dub can say it
Here is some custom callsigns you can set and it will be said in the speech!


For mission making:
You have two default vehicles for each faction in the game, one airborne and one ground radar, they have increase radar about half the size of a real AWACS, they are also available in Zeus.
You can also convert vehicles to an AWACS with a module in both the editor and Zeus, and the condition is that the vehicle must have a radar and crew.
You can also convert vehicles with a function: [this] spawn RTG_fnc_MakeVehicleAWACS;
You can set the Home plate and Bullseye by adding to the variable of markers AWACSbulls and AWACSHome, I recommend not do that for multiplayer PVP since those variables will work for both sides, instead let the player set their own markers.
You can mark vehicles as tankers with a module, also as zeus, but vehicles that have "tanker", "IL-78" or "IL-76" in the name will be consider tankers.

For the dub language, the default voice is English, but if you play as a Russian speaking character it will change to Russian.
