Suggested kill/death streaks

Beginners:

How high of a kill streak do you usually get? if when you get a 5 kill streak you feel very good then i highly suggest using uav, care package, and sentry gun. If you often get a 5 kill streak but usually you die before 6 or 7 i highly suggest (uav, OR care package), predator missile, and precision airstrike. Keep in mind uav is good to have for the airstrike but care package can give you anything maybe even something good like pave low, ac-130 or chopper gunner. If your feeling very lucky and you think you can get a double kill with the preditor then you may want to take the chance to switch the precision airstrike with harrier strike or attack helicopter.

Intermediate:

If your the person who consistently gets a 5 kill streak on your own with no care package help but you cant seem to get a 6 or 7 kill streak often then i highly suggest using predator missile, then your choice of (precision airstrike, harrier strike, or attack helicopter) and for your final kill streak use emergency airdrop.

Advanced:

If your a pro and you can get 7, 8, or even 9 kill streaks on your own i highly suggest these kill streaks, (harrier strike or attack helicopter), (pave low or stealth bomber, i suggest pave low), (chopper gunner or ac-130) chopper gunner seems to get me more kills then the ac-130

If your advanced and feeling lucky:

If your good enough to get a 9 kill streak and not die or your feeling lucky, very lucky use pave low, chopper gunner, and tactical nuke.

The reason for choosing these kill streaks, anything you get out of a care package, emergency airdrop, the sentry gun, or something you have got during your last life will NOT add on to your kill streak but the predator missile, precision airstrike, harrier strike, attack helicopter, pave low (works 1/2 the time), stealth bomber, and chopper gunner will add to your kill streaks to assist in getting your next one, the ac-130 i'm not sure about i have never been able to get enough kills for the tactical nuke with it and i never use emp. use your kill streaks during your current life if they will earn you another but use them wisely such as don't use airstrikes unless someone gets you a uav.
