I'm sitting at a proud 32. 
  
 Edit: Make that a 39 for my 4th nuke. I tried a pavelow instead of harriers this time, and the pavelows are just Godly.

What's yours? 
 
 
Also, to fix this bug, we should be allowed to type in the name of the forums we want to post in...we can obviously see when the bug will happen.

35, i have a friend on 52 though.

I have over 50.. I think.. haven't played in a minute

23

" 23 "

21. Got knifed while chopper gunning. Could have had a nuke but no, someone happened to look at the random spot no one ever looks into. I seriously have the worst luck sometimes in MW2.

I also have a 32

31 but I don't use nukes.

32 but that was by cheating, shame on me lol.... but probably really in the low 20's i suck at killstreaks, thats why I love my care packages

Painful if you were going for a nuke. "

26 here.  I have no hopes of legitimately getting a nuke.

25, no nuke equipped :(

" 25, no nuke equipped :( "

31 without nuke. Had 24 with nuke equipped and then got knifed laying in the most secluded spot I could think of. I've never gotten a nuke >_>

32. predator, harrier, chopper gunner. m82a1.

I got 36 with harrier and chopper gunner while using the intervention.

24.

All these 24s are hilarious.

My highest kill streak is 35 i think. I don't really go for high kill streaks unless I'm going for a nuke. And I only go for a nuke for the challenge.

My best is 4 1/2 inches, in a hot shower.  Fully shaved.

27 with no nuke equipped. I had just prestiged so I hadn't unlocked it yet. I had Predator Missle/Harrier Strike/Pavelow as my Killstreak rewards. Still haven't gotten a nuke, though I never have it equipped anyway.

8, bitches. Fear me.

Mine is 44. Chopper gunner on Afghan is silly.

You think your shits bad!? I shot somebody will the 50 Cal. in hardcore at a 24 killstreak and the bullet missed completely...the crosshairs were right on him!  That cost me my first nuke. I got another though, so it's all good. 3 total. "

Only 32 I think. I used the nuke straight away as soon as i got my first one.

 my longest killstreak was around 15 or 16

I think it was 24-25

34 on Overpass.  Predator, Harrier, Pave-Low.  The Pave-Low got me 10-15 kills alone.

2. hell yes

Like 16

28.  I had predator, harrier, EMP

7.

I think it was around 18 or so. Got really, really lucky. I think it was Predator Missile, Harriers and Stealth Bomber, along with an ACOG'd Intervention + Stopping Power. It was awesome.

Mine is 24, a friend got 28.

41. Chopper gunner on Afghan.

Nuke boosting with a friend.

31, sniping in wasteland

i'm not good :P 

21, Really is too hard to get anything worthwhile with all the tubes and what not. Plus my play style isn't conducive to long kill sprees.

21. I've been going for the nuke for a while now. I'm trying pavelow, chopper gunner and tactical nuke, but even when I get the pavelow and chopper gunner, I can't seem to hit 25.

18. I play a slow and stealthy game, or a very quick paced sprint to flank the enemy with my UMP which often leads to smaller streaks.

mines 37.
predator, harriers, chopper gunner on afghan ground war.
the entire enemy team just decided not to shoot it down and keep running from out of cover.
was pretty fun ^^
