Having weapons with ranges so different isn't a good idea, to my mind. If you do have several more bodies, I'd advise you to give 2 ML to tacticals and build a third Tac squad with either MM or Lascannon - the points would be nearly the same, but you'd get fire-splitting and some variants for target-choosing.
Without both transport (or Rhino-propelled teleport homer) and a heavy gun (Cyclone or Assault Cannon) they aren't much threat both in CC (can be evaded) and in firefight (soak/evade/armor save - whatever).
What is his place on the battlefield? What squad with?
It has too little heavy weapons to be a proper gunline and is too slow to be something else. Maybe the list is built of lefotver models but it's perspective isn't too good, I'm afraid.
