I'd like some more choices in SMGs

As above. Right now, we pretty much only have the MP7 (Fantastic gun) and the Uzi (Rubbish gun). I'd like for the UMP45 and possibly the MP5k from Insurgency 2 to make a return for security.

Although, I'm not sure what other SMGs the insurgents could get. I'm open to suggestions.

The uzi is horrrrrible.
