The kill streak I use is:
5 Kill streak for predator missile
7 kill streak for harrier
11 kill streak for chopper gunner/AC130
If you have problems getting these kill streaks try using the perk Hardline to lower the kill streak necessary. Use weapons you're comfortable with (Assault guns being the best). Try not to run into the middle of the map or into a heavy fire zone as this will cause a higher chance of death. I do not condone camping so please to not consider that. Be cautious and good luck!

Prestige mode removes all perks, weapons and kill streaks leaving only your accolades. What prestige mode does is shows other players that you reached the highest level and started again from the bottom, thus proclaiming your l33tness.
