CHAPLAINS AND INSTRUCTORS USING AUDIO-VISUAL MATERIALS
I have found in my own experience on the platform, that many new audio-visual materials and methods are now available for the Instructor in the 21st Century.  Instead of dusting off your college notes and lecturing your students, it would be better to learn the material and present it more from memory.  Adding audio-visual materials can assist you in this endeavor.
Do I need to create my own PowerPoint programs or rely on those already available?  The answer is "yes" to both questions.  There are many short videos available in the public domain (some are illustrated on this page) and can be incorporated into your lesson material.  PowerPoint programs can be created from 'scratch' by utilizing the photo/video materials already available.
Let's look at some of the short video films taken from actual combat during WW2 and see examples of what is available to use.
