are some of these different versions of the same book?

So I have been reading some of Damien Lewis`s books lately, he has A LOT of them about the SAS, but I am wondering if some of them might be the same book, just in different versions (Later release or different publisher?), or if they are all different books, anyone know for sure? These are the books I am a bit unsure about:

Damien Lewis:
- Churchill's Secret Warriors: The Explosive True Story of the Special Forces Desperadoes of WWII
- Churchill's Secret Warriors - The Ministry of Ungentlemanly Warfare
- Churchill's Band of Brothers: WWII's Most Daring D-Day Mission and the Hunt to Take Down Hitler's Fugitive War Criminals
- The Ministry of Ungentlemanly Warfare: How Churchill's Secret Warriors Set Europe Ablaze and Gave Birth to Modern Black Ops
- Churchill's Hellraisers: The Thrilling Secret WW2 Mission to Storm a Forbidden Nazi Fortress
- Brothers in Arms: Churchill's Special Forces During WWII's Darkest Hour
- SAS Forged in Hell: From Desert Rats to Dogs of War: The Mavericks who Made the SAS (I believe this is the follow-up of "SAS - Brothers in arms"?)
