This episode covers the Tonkin Gulf incident and the arrival of US combat troops, in the 1964-65 time frame. That means there is plenty of combat to fill the time.

Once again, what was missing is more important than what was shown. Because what was missing would have given more weight and context to the anti-war movement. I am assuming that the narrative of this series is chronological. If he jumps back in time in later episodes, I will rethink these comments.
