So, just learned an interesting fact that makes getting ahold of all those greedily protected missions easier.
A trk file is saved in Saved Games/DCS/Tracks/Multiplayer when you connect to a server. A trk file is really a miz mission file with some track data added. You can literally do as little as rename mission.trk to mission.miz to reuse the mission...
