How do you get the preditor missile in cod MW2?

U have to get 5 kills with the assault strike package, then press the button that activates ur predator. It should show up with "Predator Missle ready for deployment" or similiar. Once u have got 5 kills, even if u die, the pred will stay with u. If u die before getting 5 kills, then the killstreak counter gets reset to zero, and u have to start all over again. That is why I use the support strike package, cause even though it doesnt really damage enemy team, it doesnt reset. ;) hope this helped
