New weapons that should be added

I feel like we need an AT rifle for the recon class. It should be easier to take down tanks as recon without getting right up against it. I don't have trouble getting close enough to one when I'm playing agressive with a shotgun or carbine, but when I play sniper and constantly get killed by a tank far away then it isn't fun. It would of course also work on aircraft. I also think it would be fun with a full auto shotgun, like the AA-12 or something. What do you think?
