All this stuff gets vetted by the deployed units themselves and then by the operational-level HQ before being released to Media Ops. That is very different from people "mouthing off" on here with no oversight, as was happening a week ago!
I also suspect that the (very detailed) information being released is part of a campaign to show Gadaffi's remaining forces that their only chance of survival is to defect now. Just as he is trying (unsuccessfully) to show that we are killing his civilians, in order to fracture the coalition. When he does it, it's called propaganda; when we do it, it's called Info Ops
. Obviously someone has decided that the risk to OPSEC is outweighed by the possible operational advantage to be gained... we'll see...
