Course Materials

This instructor-led course has pre-course work (estimate 4-8 hours). Additional information about the course can be found on the Overview page.


The pre-course work is a professional reading assignment. Students are required to buy and read the material in advance of the Instructor-led portion of S-339. The Cadre will lead a discussion based upon information found in the book. This information will coincide with the learning objectives for this course. 

Students will be called upon individually or in group format in order to render opinions based on the following reading:  The Mission, the Men, and Me: Lessons from a former Delta Force Commander​ (New York: Dutton Caliber; 2008), Pete Blaber

  • Written by a retired Delta Force Officer, the book highlights the guiding principles and insights gained through a career of Special Operations around the world.
