Aha, thanks. I guess I'm remembering the old Jane's series where you could give an "Affirmative" to the wingies' call.
I actually had a MiG-21 to the rear of the flight & told the other element to clear their six- I assumed at the time they would shoot whatever they found. However, they asked permission first, so I tried to get a padlock so I could tell them to "Engage my target". Before that happened they both called "engaged defensive", & then they got smoked.
