What is the difference between a 'baffled' liquid tank and an 'unbaffled' (smooth-bore) liquid tank?

  1. Baffled tanks have external radio speakers; unbaffled tanks are silent
  2. Baffled tanks contain internal bulkheads with holes to slow down front-to-back liquid surge; smooth-bore tanks have no internal dividers (often required for sanitation, like milk/food)
  3. Baffled tanks carry solid gravel only
  4. Smooth-bore tanks can never be transported on roads
