Was just curious if someone knew how to do this if its complete all unlock everything for it or what if anyone knows it would be a nice help so thank you if you have info and if this is the right place to ask for this?

Scroll down a bit, they will explain how to get the callsigns. Basically you get one if you have all attachments, then after you Prestige'd you can get more by getting kills
