Thanks for all the tips and input. I feel as though I owe the team one, but being a new player and member, I don't have much to contribute.
One thing I've been enjoying, which may not be for everyone, is using the Kinect for Voice Commands.. That extra step of using your bumper to command and request from teammates has had me killed on a few occasions.
Also, maybe I missed it, but being aware of dead and alive squad members is key. When pushing an objective, it is always nice to have a squad member to spawn on close to your teams current progress. An alternative (credit to Nesty for the idea) to relieve all the pressure from our lone surviving soldier is having one squad member carry and use a Soawn Beacon.
Cheers!
