How to stock grind the F-15E?

So I just bought this plane, and the stock grind is painful. I don’t get why people always chase me like there are some other targets. I have to keep notching 0 chance of fighting back; the most annoying part is that missile come from a different direction. Every match I just end up notching 15 missiles. So since the major issue I am facing is that there will always be 2 or more people chasing me for no reason and spam a tons of missiles at me… like do they have type of things that automatically knows that my plane is fully stock?
