I made a mission with a range of SA-10 units 100 miles away from me. I'm not really familiar with the model numbers but I think this included a launcher, a command unit, a search radar and a tracking radar. I flew in at 25,000ft until the RWR receiver picked up a CS warning. I then dove to about 100ft and used terrain masking until I was 5.5 miles away. Then I popped up and launched a maverick on the launcher. It seemed too easy though.
I think I might have not put the units in correctly though - how do I make sure that the radars and launchers are connected and talking to each other?
