This might have been asked before. I try to searching, didn't find it.
I was flying around in Apache Longbow and I see the outline of 2 helicopters maybe 3 km in front of me flying by. from right to left,
I had my air radar on set to ALL and 8 km.
My air radar was blank except for my one wingman.
Then I put my ground radar on Medium and they showed up on it, two MI-24
I couldn't shoot them with my stinger because they are not on my radar. So I told my wingman to attack them and he shot one down with a stinger and the other one got away.
So why did they show up on his air radar and not on mine?
