My 2 cents on strategy.... Options

The most common mistake I see new players make is not taking time when they move around. If you watch MOB, and some of the better players you will see that most of the time we are careful when we walk around. Hug the wall, look out from the doorway by leaning around the corner, crouch and lean when you can. Take your time and don't just charge around. Think when you are about to go in a room or area where someone could be and account for that. If you watch real military people you will NEVER see guys just bullrushing in somewhere and it is a good way to lose your life quickly.

Lastly I like to use the bait and move tactic alot. Hide somewhere and start shooting people, then retreat and move to a spot that allows you to observe the place you just left. Almost always someone will "come after you" an think you are in the same place.

just a little add in on FK's comment about bait and move smoke is a good bait to use I like to toss a few smoke in one room and go in the one right next to it or hide in the corner works all the time a player will come charging in the room guns a blazing and all I have to do is sit there fire at the muzzel flash
