They can any type of from a soldiers personal memoir to an in depth overview of a particular battle. The only thing I'm not interested in reading would be a book that gives a broad overview of the war in it's entirety.
As an example, here are some books I recently finished reading that were all incredible to read.
Stalingrad by Anthony Beevor (absolutely, positively great read. Could not put it down.)
The Pianist by Wladysaw Szpilman
With the Old Breed by Eugene Sledge
The Ghost Mountain Boys by James Campbell.
Thank you all for any suggestions.
Have you seen the World War II AskHistorians book list at https://www.reddit.com/r/AskHistorians/wiki/books/wwii? Most of them are indeed general-purpose books, with titles like "... in the Imperial Japanese Navy 1887-1941", but there are at least a few specific ones.
One that I saw recommended several times, and read myself, is in "Naval Operations": Shattered Sword: The Untold Story of the Battle of Midway. I thought it was very good, especially because it debunks the established story that's been maintained for decades, but that's a naval battle, and all your examples are on land.
There are others that are on land and limited in scope, or mention interviews and memoirs (the one on the Gothic Line, Robert Gildea's book on the French Resistance, et cetera).
Not a moderator, just another reader: if you get a reputable suggestion, maybe message the mods to bring it to their attention?
