Paveway - Loft Bombing
" When you employ these weapon delivery techniques you will find that the Paveway is extremely effective, yielding probability of kill ratios between 85% and 100%. That means at least six or seven kills from a maximum load of seven.
During you approach, it will be possible to use terrain masking to maximum effect by running in from dead ground, with a previously acquired lock, and then popping up over the terrain just prior to weapon release. This type of attack affords even more protection, but unfortunately the terrain rarely cooperates in providing an ideal attack route, and the ability of your onboard systems to hold a lock with a broken line of sight is not consistent.
Even so, bearing these factors in mind, will enable you to make good decisions during your mission, and should increase your combat effectiveness, while reducing the level of damage sustained during such attacks. "
