ever notice most of the time gunners go right up to a wall and start to fire on it being exposed to more weapons but they should do it from a distance where it typically is safe. I know the reason why... pirates don't target walls they target objects beyond the wall so when they encounter a wall they decide to go around it or shoot through it. The problem is they make this decision directly in front of the wall rather than in range but in a much better location. If I wanted bucs to go on the front lines i would have hired them but since i hired gunners i expect them to work down range.
