There is a much easier way that only requires 1 person and you
get into a cage match with a friend and have harriers and precision airstrike selected, then get 7 kills so you have both ready to call in
get your friend to plant a tactical insertion where the airsrike will land so you get 2 kills pre airstrike
and then repeat this
Even though you dont get the 5 kills with one it still counts of you get 5 in one match for somereason :confused:
hope i helped
