What is the easier way to get tactical nuke?

The easy way 4 a nuke is to either nuke boost with a friend or just get it by using the following kill streaks:

Harrier Air Strike

Chopper Gunner or AC130

Tactical Nuke

I recommend this following class:

Tar-21 FMJ

M93 Raffica FMJ

Flash bags + Semtex

Scavenger Pro

Cold-Blooded Pro

Commando Pro

Another user states:

I used to think AC130 was the best, but once I got used to Chopper Gunner, I realized how much better it is on every map (except the airport). I have over 10 nukes in COD so far ,,, thanks to Chopper Gunner.
