Multiple reports on multiple servers. Yesterday I hit an F-15 with 4 R-60's all back to back, and he was undamaged. A guns burst ripped him apart.
Today I hit another F-15 with a pair of R-60's from the SU-25A, zero damage. After one turn he hit me with an AIM-9 and died instantly.
I also had a flight where in an Su-27 I was hit by 3 missiles in rapid succession, zero damage. One turn, R-73 killed the Mirage.
I have recordings if needed.
