Title is fairly self explanatory. If the new LMGs get it why shouldn't the DM and sniper classes get one? It would improve the DM class which is currently fairly useless in the face of the new SAWs, by allowing them to set up in places where they are actually usefull. I mean not everyone shoots from a prone position, they stack up boxes or what-have-you and set up back in a room.
And of course the Sniper class could do the same (even though it seems no-one likes snipers

)
I can elaborate more on the idea If you want, but i mean come on... its simple.
the only problem I foresee is with ammunition, as each mode would have separate ammo.
Thoughts?
