Wingmen

Datalink
Allow users to share specific data with other aircraft, like currently Locked on aircraft, Friendly aircraft, and any extra data set by the creator of the aircraft.
This would be helpful with Wingmen ontop of the 'Mark As Friendly' system, as you can tell wingmen what not to fire on along with tell your wingman what aircraft you are focusing lock on. This can be applicable to Multiplayer as well. [Datalink aircraft that are locked onto a target you are not locked onto will show that target as Orange]
