Hello and happy new year!
I am currently in the middle of the campaign and just finished Mission 5. It is super interesting to see how those trainings were structured and I already learned a lot about the MiG-21.
One thing, that is a bit frustrating though is, that the AI ignores the hard deck completly. If I manage to get behind my enemy they just dive to the ground and the fight is terminated, when I hit 12.000ft. This might be a limitation with DCS or maybe it broke with some update, but it just feels unfair and unrealistic, especially when everything else in the campaign is so well done.
Is there a way to fix this? If not you might want to think about offering the option to ignore the hard deck via the F-10 menu like
1. Offensive BFM
2. Offensive BFM (No Hard Deck)
