Both is often a safe bet :)
Before I cry over hundreds of mirage kills that took 3 missiles....last night I started learning the mirage myself also to understand why I get team killed every day by them.
While flying straight in the editor and playing with the radar modes I got hit in the face with 4 REs.
After 3 I could still manouver as if the plane was new. The 4th did finaly make it difficult to land. Perfect aircraft to white weasel or drain air defences :)
Besides that I'm impressed, its a really fun plane!
