your next assignment - Clauswitz, "On War"
http://en.wikipedia.org/wiki/On_War
After that you really should read First to Fight by Krulak (the elder) great book of our history...required reading for all Marines by the Commandant.
I remember all the required reading.........the first two mentioned here were primary. Had a Battalion Commander during my last tour in the ROK who required us to read "We were Soldiers Once, and Young."
Though they've been there as long as I can remember in some form/fashion or another, toward the end of my career there were many, many, many, many, many updates and changes to Army Field Manuals (FMs). Seems passages from some of these works became more apparent and frequent with the new editions and completely rewritten manuals.
BTW, just noticed your avatar, Sean. I think it is neat how titles differentiate between the Services. In the Army, every rank is abbreviated to three uppercase characters. And though there is no written guidance, per se, on the use of or directed use of indicators of impending promotion, it was customary to use the three letter abbreviation of one's current rank followed by the letter "P" in parentheses to indicate "Promotable." For instance, in the Army, a Major selected for promotion to Lieutenant Colonel might list his rank as "MAJ(P) Cary."
Now........all that funky stuff they speak and write in the Navy is a complete mystery to me...........everything is an acronym.
