Example .... I get 3 kills and get my Spy plane. Before I get a chance to get to a safe spot to call in the plane, I have contact and I kill 2 more players and get my napalm strike. Is there any way to use to the spy plane first ... then the napalm strike? It seems that there would be and the "message" of the day even tells you to use them in conjunction, however I do not know how to go back and use previous kill streaks when you've earned others after. Thanks!
