What analogy does Pyle use to communicate the idea that most people at home have an incomplete comprehension of what war is like?

Pyle uses the analogy of a movie to illustrate that most people at home perceive war through a distorted lens, much like watching a film that captures only selected scenes and emotions. Just as audiences cannot grasp the full depth of a story from brief clips, those at home lack a complete understanding of the chaotic, brutal realities of war, as their knowledge is filtered through media and narratives that simplify or sensationalize the experience. This analogy emphasizes the disconnect between the lived experiences of soldiers and the sanitized perceptions held by civilians.
