Armies of the Fifth Frontier War, Impressions Not Errata

[Anstett]

For a fictional description of how devastating orbital bombardment might be, refer to Neal Stephenson's Seveneves. The Moon gets broken up and its shards come tumbling into the Earth's atmosphere. I'm not sure how if that's exactly how it would play out, but knowing what I know of Stephenson, I'm sure he did due diligence in his research.

It is a very good book... until the last third and the twists at the end.
I do believe that the first third of the book is solid science used for fiction, the middle part is good solid theory.

My guess is that it would depend on the size rocks used.
