There are more then one F-15 out there and god knows how many AIM-120 they throwed at you.
What kind of Shocks me is that you keept pressing forward. I havent played Lock on much and know very little about russian missiles. I only know what I need to know. When they fire at you, you better do defensive right away and backout and try again.
I have a lot of time in other aviation simulations and the general feeling that I got is that the AIM-120 is a bit undersimulated.
If this tactics (keep pressing forward) are commonly used by the experts of the Mig-29 and Su-27, 33 etc, then its worse then I though.
A note though.... I tend to fly both the F-15 and Su, but my lack of knowelage of the russian missiles and avionics etc I tend to fly the F-15 and are more successfull with the F-15 as well then in the Mig / Su's.
The times I have flow online I have to drop all of my loads on 1 guy to keep pressing him and then hopefully kill him with AIM-9's. Also in those situations the oponent didnt go defensive in any way.
