I completely agree with this feedback.
I was playing few times some MP missions with a friend,urban fights were horrible.
Because even, if the bad guys were on the other side of the city, I was hearing the sound of their shot, as if they were right next to me.
It's the same with the satchel charge. I was hearing the bip bip of a man putting a charge, as if it was less than 1 meter from me, but it was, 300 meters from me.
