Not sure but i know i got it really early... my best guess would be try playing some different game types... maybe that corresponds with being a "specialist". I just know its one of the first titles i got. If you really are having trouble, there are big lists online of how to get each title. Look em up.
Kill 10 enemies with a single kill streak. For example if your kill streak was a chopper gunner you need to kill 10 enemies with that one chopper gunner.
2500 Headshots ( yes i did say headshots :D ) I have it its pretty epic Xbo Live Gamer Tag: FLuX SteaLth Add me <3
Reach Prestige 1 and Level 69.
Get stabbed by someone who has that title set as his active callsign.
you have to get 250 kills with melee
No
Get to ninth prestige
Use a title that is really hard to get. Such as a 2500 with the spas 12 title Thats what I have ;)

You have to call in two EMP's.
prestige and get to level 35
I believe you get it for calling in 50 uavs.
