No, your style of playing will not affect you in any way. It is simply buttons being switches with their uses. If you make sure to check everywhere you can for enemies then you will make it through. What I did, and I cannot believe I remember this, is run along the wall to the right and kill the guys in the courtyard with nightvision and silenced M4 mix. Afterward, I went along the wall to the left and climbed up the ladder and killed all the snipers up there.

Only other hard part of this level is getting the wife to the helicopter. Make sure you do not accidently shoot her when you first bring her outside that building. Also, make sure everyone is dead before you do so. I had Bravo hold position and fire at will at the entrence to the wife's holding area. After that I went off to kill random stray terrorists. After the extraction the rest of the map is easy, just stay focused and look for the enemies.
