Basically it is a get into your face fast list, and the bomma flies around taking out targets of opportunity and being a distraction.
The bomma has actually shot down enemy fliers, and has scorched many targets on the ground. It is mainly anti infantry and non vehicle heavy support stuff (like devastators, etc). It has a 70% survival rate so far and has actually earned its points back in most of its games. Like making a dead on hit with a bomb right on a DE HQ unit wiping it out and earning a kill the warlord point. (it was great fun to see the look of my opponent as his 200+ point death star unit burned up)
I always try to find a two target run. That is to find an enemy unit to fly over to drop a bomb on, and a second unit that I can shoot missiles at. While not the most scientific and concise tactic it does seem to work out well most of the time.
Hope that is what you were looking for.
