2Max_Caine and kabill
Thanks so much guys, looks like it's working!
I have another question: If I want to arm Mig-31 and Marauder with 4 rockets instead of 2, how will I do this?
I put in aircrafts.xml airplane.human.mig31 in "HeavyWeapons" column 4 instead of 2, however in the game Mig still has only 2 rockets.
