This video does a great job at explaining how the term Shell Shock emerged after World War I. It also does a good job at explaining how the military community had a hard time determining whether it was a physical injury or just a mental health problem. The video does a good job mentioning that the problems that effected veterans after WWI still effect our soldiers today. The main point made is that veterans suffering from PTSD (aka Shell Shock), have a hard time readjusting to normal society.
