Weapons list of badge ?

Hi,i'm a First Liutenant and I have a suggestion\question :

I don't know the prizes of all the badges,actually I have the badge Assassin B1,and i won several GP and D.E.S. for 7 days.

But some1 told me that is possible to have permanent guns ( i heard one that ,farming for elite badge,had M4 Crystal ).

Now,the points is : can you tell to player which are the prizes for every achieved badges?And if there is already a list of the guns that you win,can you link it ?:P

Thanks anticipately,

GuEsS
