Could be the case of diving behind a corpse as well. I did this just the other day on Wolf. Four shots with a K98 at three people all hits center mass with indicators. My field of view was clear but I figured the corpse I dived into was still blocking it.
And that leads me to a question (I have asked it before)... With the BF2 ragdoll bit throwing bodies around different for everyone what dead bodies count as cover?
