Flying the campaign now and I'm confused by this mission as well. I'm told to fly into the FEBA at 5700 and once I'm in the area and find the column I decide to use the loaded CBU-97's that have been loaded up by default, the only thing is that the HOF for the weapons is set to around 8500, so it goes against what has been planned, plus they take forever to drift down and never hit the column
