Not sure in BMS, but I'm cutting my teeth on AF right now. The only advantage I have found in getting low is as follows. During an OCA Strike, I'm flying NoE as I come up on the runway (target). As I get ready to carpet bomb (CCIP) the runway at 200ft./450kts I do get some SAM launches, but they tend to go ballistic immediately or simply can't turn tight enough to get me. The drawback is all the smaller AA guns are drawing bead on you here, but I have made it back to home plate plenty of times with a few holes in the plane. Can't say I ever made it back with the tail section gone! The trick is getting low and staying low. If you pop up after pickle, you will get corn holed by a SAM, so stay @ 200ft until you get out of range of the enemy fire. This won't take long @ 450kts. It doen't hurt to drop some chaff and flares across the runway as you drop your bombs. This method is only effective against big non-moving targets like bridges, factories, and runways. Also, may I suggest you only use ordinance with a drag kit so you don't get caught in your frag pattern. One more thing, this only seems to work on the first pass. They seem to be expecting you if you come back for another run and get a better gun solution on you during the second pass.
P.S. Like I said, I am cutting my teeth, (and this is AF, not BMS) so don't be surprised if some vet comes in here and blows hole in this tactic. In fact, any input on this tactic from someone more experienced is welcome.
