It was my distinct pleasure back in 2015 to get the opportunity to work with a former commander of mine, Dr. Douglas Mastriano (COL, US Army, retired), a professor of history at the US Army War College at Carlisle Barracks, Pennsylvania. Dr. Mastriano is one of the country's foremost experts on the WWI "Hero Of the Ardennes", SGT Alvin York. 

Working with Dr. Mastriano's existing slides and notes, I created the PowerPoint presentation deck he uses today for his lectures on SGT York at the War College and abroad.
