Assistant Professor Dale Eikmeier of the U.S. Command and General Staff College presents a 4-part video series on the Operational Art. The videos are around 11 minutes each and are excellent value for someone tackling the Operational Art topic for the first time.

As such, he argues that its definition is so broad that it is vulnerable to losing its meaning.
