Hi,
the problem raised is specific to human-controlled JTAC lasing for human-controlled aircrafts.
As mentioned before by others, lasing from an aircraft for another aircraft has no issue.
To reproduce the issue you need at least two person, you cannot validate by yourself.
First issue, with a dedicated server (at least two people needed):
Create a miz with a human-controlled JTAC and a Hornet.
Run the miz on a dedicated server.
Try to lase for the other aircraft, notice you won't be able to pick up the laser, no matter the distance.
Second issue on a listen server (hosted by a player) (at least three people needed):
Create a miz with two human-controlled JTAC and a Hornet.
Have one player host the miz.
Have the two human JTACs (host playing as one), on separate codes, lase for the aircraft.
Notice the player pilot will be able to pick up the laser from the host but not from the other player.
You can also reproduce the same issue with IR pointer at night.
