Unfortunately, it doesn't work. It's quite possible that this is because I'm testing everything on the vanilla version of the game. Perhaps something has already been changed in FAF, and that's why it doesn't work for me. The code I have written in both files is in the attached file. For testing, I created a nuclear mother missile that disintegrates into 10 fragments. When it disintegrates, the strategic missile defense system fires all 24 missiles, although 10 would have been sufficient. How can I solve this problem? GEB4403.txt
