HARM test results. HARM is very easy to use. Just select which threat you want to attack with the FLIR/FOV button and fire weapon. I added an air start, HARM loaded test plane in Razor's Shuttle Diplomacy mission knowing it had a good number of anti air radars. These did not turn on until I was fairly close so I didn't get to test anything at a long range. I ran 2 test flights with a full load of 4 HARMs each time. The first test 2 missiles killed the radar emitting threat and 2 missed, very close to the target ( maybe a vehicle length away at most) but not close enough for a kill. The second test 3 kills and one very close miss. So my unofficial test says they are very good but not a sure thing. Nice to have this capability though as it's much better than what we had before...which was exactly nothing. You do need to be sure of your target because they obviously will target a friendly radar too. They would lock on the friendly ships radars as I cycled through the radar signals. It's always possible that the misses were because I didn't yell MAGNUM quite loud enough though.
