In what way? During My tenure in the Corps, I had no access to airbursting ordnance. I understand that there are some that are now available to ground troops. Remember, in game, all airbursting does is to reduce Scatter. It does not negate it directly. 

I meant in game.
It turns an unguided rocket's scatter from 4d6 to 2d6, taking the average from 14 meters (over 3 times the blast radius) to 7, reduced by net hits.
Maximum scatter goes from 24 to 12. Also note that the new maximum is less than the old average, thereby making the "worst airburst can do" be "slightly better than average" without it.
I shall also note that 7 net hits is more than enough for a critical success, and yet still leaves room enough for complete failure (scatter roll of 12, minus 7, leaves 5 which is greater than the blast radius).
