killstreak qwestion

ok so i have a question about the killstreaks so i have care package and predator missile equiped also harrier strike so my qwestion is if i call in my care package and i get a ac 130 and i get 3 kills does the predator missile and harrier strike get unlocked or is the reword just the ac130

care package and emergency drops dont count on your kill streak.

"qwestion"? Are you serious?!

The killstreak will continue to build.

Killstreaks will continue to build up when using rewards such as Chopper Gunner, Predator Missile, AC130, etc etc. However, the use of these items will not give you the killstreak rewards. Killstreak rewards are gained by normal kills using normal equipment.

Do sentry guns count towards your killstreak count when you have them in your killstreak rewards for 5 kills? I was using sentry gun today and I don't think it works. Like I got 5 kills so I called in my sentry gun, then I picked up a kill and my sentry killed a person, but no harrier. It's pretty dumb if sentry guns don't count but predators do.
