Hi guys, absolutely loving the remaster - it's making me properly nostalgic! I'm struggling a bit with the Air Superiority mission; locking onto targets / having my gunner engage automatically just isn't happening! Any tips?

I'm able to complete the convoy section as I can do that with the hydras etc, but using TOWs on the tanks just isn't happening. I've tried using T/R etc. to designate or cycle targets but it won't register any of the T72s etc. around the village.
