correct as is Unit tagged as "invisible" is attacked.

Pls see attached track, the JTAC is attacked and destroyed soon after mission start.  I don't remember when I last flew this mission, but this had never happened before.jtac_issue.trk

Invisible is only for map purposes, it does not mean the unit wont be attacked. Either relocate it or add defensive support units.

Thank you, but I am referring to the ME unit perform command "invisible".  I apologise for not being clearer with my explanation.  The DCS user guide states on p 274

Invisible
Set the group to be invisible to all enemy AI units. Enabled and disabled using the ENABLE
checkbox.

This command may be useful when creating ground-based FACs in close proximity to enemy
positions as a means of simulated a well camouflaged position and preventing the FAC from
being destroyed.

It is the task queue. The FAC task needs to be completed before the options are set. So move the options to the top.

Thanks very much, that fixed it.  It's odd though as this didn't happen the last time I flew this mission (I'm almost certain it was this year).  I have a number of other missions with a JTAC set up the same way (although it and the enemies are in different positions) and it doesn't happen there.

Still, very useful advice which I'll be sure to follow in future, so thanks again.
