Here Comes Chesty Puller

Ray Harris Jr. picks up the Guadalcanal campaign with the 7th Marines' reconnaissance toward the Matanikau River under Chesty Puller — one of the most storied Marine commanders of the war, at the point where his legend really begins. Short at 22 minutes but Harris's chronological approach means the tactical situation is properly set up, and the episode doesn't waste time on filler. A good entry point if you've been following the series, though newcomers may want to backtrack a few episodes for context.
