This is in the "Commandant's Choice" section of the 2013 USCM reading list:

Plenty of classics on that list - one of my favorites is "Quartered Safe out Here" by George MacDonald Fraser. Good stuff.

Another great one is "Gates of Fire" by Pressfield

A slew of other military reading lists agree with you; it was on the Army Chief of Staff 2011 list, both the 2008 and 2009 USMC lists, and the Army "Maneuver Center of Excellent" 2011 list.
