Los besides from a units own models?
Unless you and your opponent make a house rule for it, that is correct. Note, however, that if just a spec of your opponent is visible from any part of a model, they can shoot at it. This commonly means that units are still shooting through others. However, the old adage is true "If you can see them, they can see you".
There was actually some huff about abusing your own models blocking
LoS before, and the same could still be said to be true. For example, say you want to smite something, you're in range, but there's all these other models that are closer! Well, just take two Rhinos and position them in such a way that they block Line of Sight to every enemy model other than the unit you want to actually smite. Congrats, you now have a "targeted" Smite (since Smite hits the closest VISIBLE enemy unit, and only that enemy unit is visible).
