USMC Commandant's 2020 Reading List.
This year I am finishing up the Harvard Classics and am looking for a new view point. https://www.myharvardclassics.com/categories/20120612_1
Unfortunately, the military only publish on New Years Day (traditionally as a sort of holiday gift to those under command), so the 2020 list is not out yet. Every title is free via either the base library or the Navy Digital Library. Most have free audio book narration. There are discussion guides also provided for free. The website is very easy to use and poke around in, I'd suggest looking at it from a Dev standpoint alone. That said, the 2019 list is here: https://grc-usmcu.libguides.com/usmc-reading-list
There are a LOT of titles so here are the Poolee through PFC levels:
Poolee:
BATTLE CRY by Leon Uris
CORPS VALUES by Zell Miller
GATES OF FIRE: AN EPIC NOVEL OF THE BATTLE OF THERMOPYLAE by Steven Pressfield
GRIT: THE POWER OF PASSION AND PERSEVERANCE by Angela Duckworth
STARSHIP TROOPERS by Robert A. Heinlein
PFC through Lance Corporal:
CHESTY by Jon T. Hoffman
ENDER'S GAME by Orson Scott Card
THE LAST STAND OF FOX COMPANY: A TRUE STORY OF U.S. MARINES IN COMBAT by Bob Drury
THE MARINES OF MONTFORD POINT: AMERICA'S FIRST BLACK MARINES by Melton Alonza McLaurin
ON CALL IN HELL by Richard Jadick; Thomas Hayden
READY PLAYER ONE by Ernest Cline
RIFLEMAN DODD: A NOVEL OF THE PENINSULAR CAMPAIGN by C. S. Forester
THE WARRIOR ETHOS by Steven Pressfield
The 2020 list should have some froth in it (Greitens likely won't stay, but who knows, judge the art not the artist). I think it'll be a good look into a Corps that has been punched for a long time in Afghanistan. Still, some great titles in there.
