Okay, so you probably messed up the navigation, because there is no AAA gun at the IP T junction. You were somewhere else.
what runway did you want to hit? Your target was the SA-3. More specifics in the briefing
Yes, the OCA guys almost always take care of the bandits....almost. It's slightly randomized, be prepared to defend yourself, or run. It’s the point of training
There is only 1 track and 1 tanker with boom, and the tacan is on the kneeboard card if you want to make sure you hit the right one - the other one has baskets.
The radio control is never given to you automatically. I’d really need to see a playthrough video to know to figure out what you missed.
