Super Fleet adds a row of 7 even darker blue projectiles to the previous tier, but deals less damage. This gets to the point where the Fleet family can destroy a fair amount of terrain, capable of hitting enemies behind small walls.
Squadron adds a row of 5 blue-violet projectiles to the previous tier, and it deals the same amount of damage (per projectile) as its predecessor. As before, good amounts of terrain can be broken with this weapon.
