Me and mine tend to play lots of tight, close, fast maps; and we try and stay knit and clean: here's what I use to keep up with the monsters we've got...
Prime: Silenced, always, and either a PDW-R, or Ace on assault/med. I like to use the Coyote sight, and a potato grip.
Reload safety: Swagnum, SW-40, red dot sight
Equipment 1: Medkit bag
Equipment 2: 'Fibs
Nades: Impacts, you can aim them a good bit better, and there's no time to run further.
I don't play too fast, I like to pie my corners and doors, eat my health blocks, and utilize cover as much as possible. I love the Kinect sway function for this...
Stay in contact with your battle buddy and move forward like immortal fury!
