It's an even better book - especially if you have any familiarity with the genre of soldier's memoirs, which often follow a very similar trajectory, from pre-military life to boot camp to the first brush with combat, to the climactic battle.

The philosophy is somewhat different, but the spiritual and thematic successor to Starship Troopers, Armor by John Steakley[1], which I think is an underappreciated classic.
