The Past as Prologue.
During my time at the Army's Intermediate Level Education (ILE), which is a course required for all Captains and Majors for promotion to LTC, our history professor titled his course: History: The Past as Prologue. As we explored the Profession of Arms, the underlying message is that history repeats itself throughout the centuries. The past is our prologue.
I am a history buff, and enjoy learning from those who went before us. The men and women who have pioneered human advancement are models for us to continue to reach further.
