Tiles are much more fragile than some of the ablative materials out there. But, yes, they are not impervious to damage, but more tolerant of it.
Honestly, don’t you think the missile makers have thought of these limitations?
Works the same way damage wise.
Thermal energy doesn’t care what the material is at 4600mph, a defect that allows heat buildup is still a defect.
Again, damage is damage, it will do the trick.
