Presuming that what you wish to achieve is for the Iranian air-defence group to teleport around its deployment area every 15-minutes of game time whether engaged or not, your set up accomplishes this as you noted. I don't understand what the problem is now since only Iranian Group 2040 is highlighted on the Teleport Action and watching the event fire using the God's Eye mode, it is the only thing that moves.
Sorry, I have no idea what this
I was unable to notice that the units of both sides were present
actually means.
Second question = No, or at least none that I know of. Making sure that your teleporting units have unique names is a good way to keep it all straight. The list seems to populate based on the sequence that units are added and while some sort of filter or sorting system might be nice to have, with a little care and attention on the part of the scenario author they are really unnecessary and the Dev's probably have more important things in the to-do list.
