Ok so we have...

1000 Sentry Gun title
1000 Predator Missile title
1000 Precision Airstrike title
1000 Attack Helicopter title
1000 Pavelow title
1000 Stealth Bomber title
1000 AC130 title

But why not (1000 kills) with an IMS + (1000 kills) with a Reaper??

I think having them and not giving a title is pointless? anobody else!!
People use a reaper to get an AC130 but why have an IMS as a kill streak? i would use it if you got 1000 kills title

Just a thought...
