Kill 50 enemies with a weapon that has a silencer equipped. Be sure that you are prestiged. Oh, by the way, the title is "Silent Veteran" with no '2' in front of it.
Foot steps are silent
Reach Prestige 1 and Level 69.

Get stabbed by someone who has that title set as his active callsign.
any sniper with a silencer
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 ;)
