F3s
What about F3s being shot at in Deny Flight - they were the first combat aircraft to arrive in the Gulf in 1990 and they have sat on QRA continually for over 20 years.
That said, you don't have to have been shot at to be of use and be operational.
All forces have a role. I would rather keep the SAR force than the Reds if I had to choose - ideally I would keep both!
