Forum:How can I get the Intervention title and emblem?

I enjoy sniping, lately I've been using the Intervention, and really want the golden title that states 'Intervention', along with the emblem that also states 'Intervention', but has a little target underneath the word.

Unfortunately, none of the titles or emblems for ANY weapons are in the callsign article along with the challenges needed to receive the titles and/or emblems.

So, long story short, I want the Intervention callsigns but I don't how to get them. Help?
